Crystal structures and spectral studies of [Ph3Sn(O 2AsMe2)], [Bu2ClSn(O2AsMe 2)] and [PhClSn(O2AsMe2)(μ-OMe)]2

[Ph3Sn(O2AsMe2)] (1) and [PhClSn(O 2AsMe2)(μ-OMe)]2 (3) have been synthesized by treatment of Ph3SnCl and Ph2SnCl2 with Na(O2AsMe2) in methanol, respectively. [Bu 2ClSn(O2AsMe2)] (2) has been prepared by the reaction of Bu2SnCl2 with HO2AsMe2 in methanol. X-ray diffraction studies show 1 to crystallize in the monoclinic space group P21/n with a = 699.8(1), b = 1961.4(2), c = 1433.6(2) pm, β = 95.17(1)°, and Z = 4. 2 also crystallizes monoclinic in the space group P21/m, the cell parameters being a = 480.6(1), b = 1992.7(2), c = 808.8(1) pm, β = 103.726(5)°, and Z = 2. Both compounds form infinite chains with alternating (Me2AsO2)- and (R3Sn)+ or (R2ClSn)+ units. The dimer 3 consists of 8-membered (OSnOAs)2 rings in which the tin atoms are bridged by methanolate bridges. It crystallizes triclinic in the space group P1 with a = 822.8(2), b = 910.4(2), c = 929.2(2) pm, α = 77.04(3)°, β = 82.35(3)°, γ = 68.69(3)°, and Z = 1 for the dimer. The vibrational and mass spectra of 1, 2 and 3 are given and discussed.
