Carbophosphazene-supported ligand systems containing pyrazole/guanidine coordinating groups

Carbophosphazene-based coordination ligands [{NC(NMe2)} 2{NP(3,5-Me2Pz)2}] (1), [{NC(NEt) 2}{NC(3,5-Me2Pz)}{NP(3,5-Me2Pz)2}] (2), [NC(3,5-Me2Pz)]2[NP(3,5-Me2Pz) 2] (3), [{NCCl}2{NP(NC(NMe2)2) 2}] (4), and [{NC(p-OC5H4N)} 2{NP(NC(NMe2)2)2}] (5) were synthesized and structurally characterized. In these compounds, the six-membered C2N3P ring is perfectly planar. The reaction of 1 with CuCl2 afforded [{NC(NMe2)}2{NHP(O)(3,5-Me 2Pz)} · {Cu(3,5-Me2PzH)2(Cl)}] [Cl] (6). The ligand binds to Cu(II) utilizing the geminal [P(O)(3,5-Me2Pz)] coordinating unit. Similarly, the reaction of 2 with PdCl2 afforded, after a metal-assisted P-N hydrolysis, [{NC(NEt)2}{NC(3,5-Me 2Pz)}{NP(O)(3,5-Me2Pz)} · {Pd(3,5-Me 2PzH)-(Cl)}] (7). In the latter, the [P(O)(3,5-Me2Pz)] unit does not coordinate; in this instance, the Pd(II) is bound by a ring nitrogen atom and a carbon-tethered pyrazolyl nitrogen atom. The reaction of 3 with PdCl2 also results in P-N bond hydrolysis affording [{NC(3,5-Me2Pz)2}{NP(O)(3,5-Me2Pz)}{Pd(Cl)}] (8). In contrast to 7, however, in 8, the Pd(II) elicits a nongeminal η3 coordination from the ligand involving two carbon-tethered pyrazolyl groups and a ring nitrogen atom. Metalated products could not be isolated in the reaction of 3 with K2PtCl4. Instead, a P-O-P bridged carbodiphosphazane dimer, [{NC(3,5-Me2Pz)NHC(3,5- Me2Pz)}{NP(O)}]2 (9), was isolated as the major product. Finally, the reaction of 5 with PdCl2 resulted in [{NC(OC 5H4N)}2{NP(NC(NMe2) 2)2} · {PdCl2}] (10). In the latter, the exocyclic P-N bonds are quite robust and are involved in binding to the metal ion. Compounds 6-10 have been characterized by a variety of techniques including X-ray crystallography. In all of the compounds, the bond parameters of the inorganic heterocyclic rings are affected by metalation.

A systematic approach to alkali biuretooxophosphates

Biuretooxophosphates represent a link between carbon nitride and phosphorus (oxo)nitride precursor chemistry being closely related to cyanurates and trimetaphosphimates. The group of alkali biuretooxophosphates has been complemented by the synthesis of four salts M[PO2(NH) 3(CO)2]·xH2O in which M = Li, K, Rb, and Cs (x = 1, 0, 0.5, 0, respectively). The structures were solved by single-crystal X-ray diffraction and compared with the corresponding ammonium and sodium salts. For all of the salts, the 1-phospha-2,4,6-s-triazine ring exhibits a nearly planar conformation with the phosphorus atom being slightly deflected. In the sequence Li to Cs, the crystal structures show a significant change in orientation leading from a parallel to a perpendicular arrangement of the rings, the latter being bridged by N-H...O bonds. The thermal behavior of the biuretooxophosphates was examined by means of temperature-dependent powder X-ray diffraction measurements and combined thermogravimetric analysis (TGA) and differential thermal analysis (DTA). Moreover, the FTIR and photoluminescence spectra of the salts are discussed.
