4,5-Bis[(triorganotin)thiolato]-1,3-dithiole-2-thione, (R3Sn)2(dmit), 4,5-bis[(triorganotin)thiolato]-1,3-dithiole-2-one, (R3Sn)2(dmio), compounds: Crystal structures of (cyclohexyl3Sn)2(dmio), (Ph3Sn)2(dmit) and (Ph3Sn)2(dmio)

The synthesis and crystal srtructures are reported of (Ph3Sn)2(dmit) (1: dmit = 1,3-dithiole-2-thione-4,5-dithiolate) and, (R3Sn)2(dmio) (2: dmio = 1,3-dithiole-2-one-4,5-dithiolate: R = Ph or Cy). The tin centres in all three molecules are 4-coordinate. Weak intermolecular H-bonding interactions are found in 1 [C-H⋯π] and in 2 [C-H⋯π and C-H⋯O].
