(4) was prepared by treating Me3SnN(SO2Me)2 (1) with liquid ammonia; single crystals suitable for X-ray diffraction were grown from a solution in liquid ammonia by slow evaporation of the solvent at -42 deg C. 2 (5) was obtained from dimethyl sulfoxide and Me2Sn2 or 1 in refluxing CCl4, the co-product in the latter case being SnMe4.The crystallographic data at -95 deg C are for 4: monoclinic, space group P21/c, a 650.3(2), b 1464.7(3), c 1479.6(4) pm, β 94.63(2) deg, U 1.4046 nm3, Z=4; for 5: triclinic, space group P, a 818.3(2), b 986.6(2), c 1119.9(3) pm, α 79.10(2), β 77.51(2), γ 77.58(2) deg, U 0.8524 nm3, Z=1.The structure refinement of 4 was based on 3092 reflections with F>4?(F) to give R=0.018.For 5, refinement using 3579 reflections with F>4?(F) yielded R=0.021.The crystals of both compounds consist of discrete (MeSO2)2N- anions and Me3Sn(NH3)2+ or Me2Sn(DMSO)42+ cations, respectively.The structures of the anions are similar to those observed in other ionic dimesylamides.In the cation of 4, the tin atom has an axially distorted trigonal-bipyramidal environment with apical NH3 molecules (Sn-N 232.8 and 238.3, Sn-C 211.7-212.4 pm, N-Sn-N 179.2, C-Sn-C 118.1-122.1, N-Sn-C 88.0-91.3 deg).The tin atom in the centrosymmetric cation of 5 displays trans-octahedral geometry with four DMSO molecules bonded through their oxygen atoms (Sn-C 211.4, Sn-O 219.9 and 221.4 pm, (O-Sn-O)cis 88.9 and 91.1, O-Sn-C 86.8-93.2 deg).The oxygen centres of the sulfoxide ligands are sp2-hybridized with Sn-O-S 121.8 and 123.1 deg, S-O 154.4 and 155.4 pm. 5 is the first example of a structurally characterized tin(IV)-sulfoxide complex in which four sulfoxide ligands are coordinated to a single tin centre. 13C, 15N and 119Sn CP/MAS NMR spectra of solid 4 and 5 agree very well with the X-ray diffraction results.In both cases, the isotropic 119Sn chemical shifts and their tensorial properties support the nearest-neighbours-environment as shown by crystallography.The slight inequivalences of the NH3 and DMSO ligands, respectively, are mirrored in the 15N and 13C CP/MASS spectra of 4 and 5.The 119Sn CP/MAS spectrum of 4 is complicated by the simultaneous presence of scalar and quadrupolar coupling of two inequivalent 14N nuclei with 119Sn.

The first 1,1′-Digallylferrocene and a rodlike, polymeric donor-acceptor complex: Synthesis, properties, and structure of [Fe(η5-C5H4GaMe2)2] n and [Fe(η5-C5H4GaMe2)2(C 12H8N2)]n

The reaction of 1,1?-bis(trichlorostannyl)ferrocene with trimethylgallium results in the formation of Fe(C5H4GaMe2)2 (1), the first digallylferrocene. An X-ray crystal structure analysis of 1 reveals a polymeric structure. NMR data confirm a monomeric structure of [1-2 donor] in donor solvents. The reaction of 1 with phenazine results in the formation of the supramolecular polyferrocene [1·phenazine]n. Its rodlike structure is proven by X-ray crystallography.

The reactivity of metal-metal bonds. II. The tin-manganese bond
Clark,Tsai
, p. 1407 - 1415 (1966)
The reactions of trimethyltinpentacarbonylmanganese with tetrafluoroethylene, trifluoroethylene, chlorotrifluoroethylene, and ethylene are described. Only with tetrafluoroethylene is an adduct, namely, (CH3)3SnCF2CF2Mn(CO)5, obtained, although trimethyltin fluoride and fluorocarbon-carbonylmanganese products are also formed. With trifluoroethylene and chlorotrifluoroethylene, trimethyltin halides and fluorovinylpentacarbonylmanganese compounds are produced, although in the latter case perfluoroacryloylpentacarbonylmanganese, CF2=CFCOMn(CO)5, is a major product. Ethylene does not cleave the Sn-Mn bond, but rather displaces carbon monoxide to form (CH3)3SnMn(CO)4(π-C2H 4). The spectroscopic properties of the new compounds are discussed.
Octahedral Bis(phenoxy-imine)tin(IV) alkyl complexes: Synthesis, characterization, and reactivity toward ionizing species and ethylene

, p. 1947 - 1952 (2005)
The synthesis of new organotin compounds of the general formula L 2SnR2 (L = N-(3-tert-butylsalicylidene)-2,3,4,5,6- pentafluoroaniline; R = CH3 (1), n-C4H9 (3)) and L′2SnR2 (L′ = Ar-(3-tert- butylsalicylidene)aniline; R = CH3 (2), n-C4H9 (4)) is described herein. The compounds were characterized by 1H, 13C, and 119Sn NMR in solution; in some cases a fluxional behavior was observed by variable-temperature experiments. Characterization by single-crystal X-ray diffraction analysis has been obtained for compounds 1, 2, and 4. The reactivity of the synthesized compounds toward ionizing agents was studied by an NMR-tube reaction. Compounds 2 and 4 underwent an alkyl abstraction reaction with the carbenium salt [C(C6H5) 3]+[B(C6F5)4] . The obtained cationic species exhibited some activity in the oligomerization of ethylene under mild conditions, producing short-chain oligomers, with saturated end groups and methyl branches.

Me4Pb and Ph4Pb readily transfer methyl or phenyl groups to an equivalent molar ratio of tin(iv) chlorides in the order SnCl4 > MeSnCl3 > Me2SnCl2 > Me3SnCl, often in a selective manner. Me3PbCl and Ph3PbCl specifically transfer a single methyl/phenyl group under the same reaction conditions to produce recovered yields in >75%. Specific transfer of 2 methyl groups from PbMe4 can be achieved at elevated temperatures and/or a 2:1 molar ratio Pb:Sn.
Formation of silicon-carbon bonds by photochemical irradiation of (η5-C5H5)Fe(CO)2SiR3 and (η5-C5H5)Fe(CO)2Me to Obtain R3SiMe
Fortier, Skye,Zhang, Yongqiang,Sharma, Hemant K.,Pannell, Keith H.

Photochemical irradiation of an equimolar mixture of (η5 -C5H5)Fe(CO)2SiR3, FpSiR 3, and FpMe leads to the efficient formation of the silicon-carbon-coupled product R3SiMe, R3 = Me 3, Me2Ph, MePh2, Ph3, ClMe 2, Cl2Me, Cl3, Me2Ar (Ar = C 6H4-p-X, X = F, OMe, CF3, NMe2). Similar chemistry occurs with related germyl and stannyl complexes at slower rates, Si > Ge Sn. Substitution of an aryl hydrogen to form FpSiMe2C6H4-p-X has little effect on the rate of the reaction, whereas progressive substitution of methyl groups on silicon by Cl slows the process. Also, changing FpMe to FpCH2SiMe3 dramatically slows the reaction as does the use of (η5-C 5Me5)Fe(CO)2 derivatives. A mechanism involving the initial formation of the 16e intermediate (η5-C 5H5)Fe(CO)Me followed by oxidative addition of the Fe-Si bond accounts for the experimental results obtained.
