Syntheses and Characterizations of (4-NH2C6H4S)4Sn and (4-NH2C6H4S)2(4-NH3C6H4S)2SnCl2

摘要

The title compounds (4-NH2C6H4S)4Sn 1 and [(4-NH2C6H4S)2(4-NH3C6H4S)2- Sn]Cl2 2 have been synthesized and their crystal structures were determined by X-ray diffraction study. 1 crystallizes in monoclinic, space group P21/m, a = 8.8431(6), b = 15.2944(10), c = 9.1974(7) (A), β = 93.835(2) °, V = 1241.16 (15) (A)3, Z = 2, Mr = 615.40, Dc = 1.647 g/cm3, F(000) = 620, μ = 1.387 mm-1, the final R = 0.0439 and wR = 0.1120 for 1892 observed reflections (I > 2σ(I)). 2 crystallizes in monoclinic, space group C2/c, a = 31.0848(2), b = 7.9685(3), c = 11.7213(4) (A), β = 97.228(2)°, V = 2880.28(15) (A)3, Z = 4, Mr = 688.32, Dc = 1.5877 g/cm3, F(000) = 1384, μ = 1.384 mm-1, the final R = 0.0416 and wR = 0.1269 for 1968 observed reflections with I > 2σ(I). The Sn4+ ions in 1 and 2 are coordinated to four sulfur atoms with highly and slightly distorted tetrahedral configurations, respectively.
