- Abstract
[Sn(S2CNH2)2S]2 ·2H2O ·EtOH ( A) was prepared via oxidation of Sn2+ with thiuram sulfide in aqueous alcohol solution. The compound [Sn(S2CNH2)2S]2 ·4EtOH ( B) crystallizes from a saturated alcoholic solution of A. The monoclinic unit cell of A, space group P21/ n (No. 14), a = 12.9169(9), b = 9.7222(5), c = 19.504(12) Å and β = 99.802(8) °, contains four formula units. B crystallizes in the orthorhombic space group Fddd (No. 70), a = 12.9500(4), b = 13.7737(4), c = 34.6012(12) Å with Z = 8 formula units per unit cell. The crystal structures consist of dinuclear Sn(S2CNH2)2 units doubly bridged by two sulfide (S2-) anions forming a centrosymmetric Sn2S2 square. These units are interlaced by primarily strong hydrogen bonds originating from the solvate molecules and the amino groups (O-H ···S, N-H ···O and N-H ···S for A and N-H ···O and O-H ···S for B). The two solvate crystals can be interconverted via their alcoholic solution. B recrystallizes after saturation and A precipitates if a suitable portion of water is added.
