, p. 1507 - 1510 (2011)
The crystal and molecular structure of γ-P4S6 was determined from single-crystal X-ray diffraction. It crystallizes monoclinically in the space group P21/m (No. 11) with a = 6.627(3) A, b = 10.504(7) A, c = 6.878(3) A, β = 90.18(4)°, V = 478.8(4) A3, and Z = 2. The structure consists of cage-like P4S6 molecules with CS symmetry arranged with the topology of a cubic close packing. Copyright

, p. 693 - 697 (1999)
The reaction of P4E3 (E = S, Se) with NbCl5 yields [β-P4S4(NbCl5)2] and [P4Se3(NbCl5)]. [β-P4S4(NbCl5)2] crystallizes in the monoclinic space group P21/n with the lattice parameters a = 6.226(1), b = 12.971(2), c = 26.380(2) A, β = 93.7(1) (Z = 4). In this compound a sulfur atom is introduced into the basal P3-ring and the resulting β-P4S4 is central unit of the complex. [P4Se3(NbCl5)] crystallizes in the same space group type with the lattice parameters a = 11.939(1), b = 18.603(2), c = 12.763(4) A, β= 90.16(2)° (Z = 8). In both compounds the ligands are coordinated to basal phosphorus atoms.

The formation of a new type of organometallic-inorganic hybrid coordination polymer from P4S3·W(CO)5 (1) and CuI has been studied. The structure of [P4S3·W(CO 5) (CuI) (3) has been verified by the combination of spectroscopic (IR, Ra-man, 31P MAS NMR) and X-ray diffraction methods. Theoretical studies of β-P4S3· P4S 3·W(CO)5 (1), 1D-(P4S3)(CuI) (2), and. 3D-(P4S3)(CuI)3 (4), which may be considered as poten-tial building blocks of 3, were carried out on the DFT level in the crystalline phase. The comparison of calculated and measured vibration modes of the P4S3 cage allows the unequivocal, assignment of the recorded. Raman shifts between 200 and 480 cm-1 and the determination of the degree of integration of P4S3 within the one-dimensional stacks of 2 or copper iodide networks of 3 and 4.

Cationic R2P5+ cage compounds (1 +) have been synthesized by the stoichiometric reaction of R 2PCl, GaCl3 and P4. The reaction conditions depend on the substituent R. Alkyl-substituted derivatives (1 a-1 d[GaCl 4]) are best synthesized under solvent-free conditions, whereas aryl-substituted derivatives (1 e-1 h[GaCl4]) are formed in C 6H5F. All compounds have been prepared on a multi-gram scale in good to excellent yields and have been fully characterized with an emphasis on 31P NMR spectroscopy in solution and single-crystal structure determination. Subsequent chalcogenation reactions of cations R 2P5+ (1 a+, 1 e+) and trication Ph6P73+ (33+) with elemental sulfur (α-S8) or grey selenium (Segrey) yielded a series of unique polyphosphorus-chalcogen cations (4 a+, 4 e+, 5 a+, 62+ and 72+ Copyright

The interaction and reaction of PCl3 and PCl3-H2S mixtures with the microporous materials Silicalite, ALPO-5, NaY, NaX, and NaA have been investigated, with the intention of producing phosphorus sulfide clusters in the pores. A rich chemistry was observed and monitored by solid state 31P NMR. The presence of P4S3, α-P4S5, β-P4S6, and P4S7 inside the NaY α-cages was demonstrated, as well as a new species that is possibly a third geometric isomer of P4S4 with C(3v) symmetry. 129Xe NMR showed the exclusion of Xe from the micropores by the phosphorus sulfides. Sulfides lower than P4S7 are small enough that they undergo rapid pseudo-isotropic reorientation inside the NaY α-cage.
Transfer of Sulfur from Arsenic and Antimony Sulfides to Phosphorus Sulfides. Rational Syntheses of Several Less-Common P4Sn Species

It has been shown that triphenylarsenic sulfide and triphenylantimony sulfide rapidly transfer sulfur to a number of the known phosphorus sulfides. The reactions are performed at or below room temperature in carbon disulfide solutions. The transfers are neither highly selective nor random, making them useful but not ideal for synthetic purposes. The moderate selectivities of the reactions have been used in the assignment of structures to two new phosphorus sulfides, structures with molecular formulas P4S6 and P4S8. The reactions of P4S3 are unusual in that products with 7-9 sulfur atoms in the molecule are formed competitively with low sulfur products. The usefulness of triphenylantimony sulfide is limited by its tendency to undergo reductive elimination of sulfur. This reduction takes the form of a disproportionation to give triphenylantimony and elemental sulfur and has been shown to occur by a second-order process that appears to involve the formation of disulfur, S2.
Products and Mechanisms in the Oxidation of Phosphorus by Sulfur at Low Temperature

The oxidation of phosphorus by sulfur at low temperatures (8 diradical. This proposal is supported by the observed rate at which the sulfldes are formed and the distribution of the sulfide product stoichiometries. Photoinitiation of this oxidation at 0 °C produces a similar array of sulfldes. The differences in the product distributions between the thermal and photochemical processes facilitate the understanding of the mother-daughter relationships between the products. The effects of oxidation by sulfur and reduction by phosphorus have been determined for several of the known phosphorus sulfides. The characterizations of phosphorus compounds in molten mixtures of phosphorus and sulfur were performed by 31P NMR and Raman spectroscopy directly on the reaction mixtures.

Phosphorus sulfur melts were annealed for one week at 673 K and then quenched in ice water. The solids were dissolved in CS2 and the concentrations of phosphorus sulfides were determined by (31)P NMR spectroscopy. Samples containing between 44 ant 70 mol% sulfur dissolved completely in CS2. Between 0 and 42 mol% remains an insoluble residue of red phosphorus. Above 72 mol% it consisted of sulfur chains linked by phosphorus atoms. The solutions contained mainly the congruently melting compounds P4S3,P4S7, and P4S10 having maximum concentrations at their stoichiometric c ompositions. Other compounds P4Sn (n=4-9) which decompose on heating, according to the phase diagram, were also found in surprisingly high concentrations. One of these was β-P4S6 which crystallizes in the monoclinic space group P21/C with the lattice parameters a=702.4(2), b=1205.6(2), c=1148.9(6) pm, and β=103.4(2)° Reaction of white phosphorus with sulfur was also investigated. In contrast to the results of previous authors, who described the system P4-S8 below 373 K as eutectic,we found that the elements reacted below this temperature.
