Structural diversity of Di and triorganotin complexes with 4-sulfanylbenzoic acid: Supramolecular structures involving intermolecular Sn... O, O-H...O or C-H... X (X = O or S) interactions

摘要

Twelve new organotin complexes with 4-sulfanylbenzoic acid of two types: RnSn[S(C6H4COOH)](4-n) (I) (n = 3: R = Me 1, n-Bu 2, Ph 3: PhCH2 4: n = 2: R = Me 5; n-Bu 6, Ph 7, PhCH2 8) and R3Sn(SC6H4COO)SnR3 center dot mEtOH (II) (m = 0: R = Me 9, n-Bu 10, PhCH2 12: m = 2: R = Ph 11), along with the 4,4'-bipy adduct of 9, [Me3Sn(SC6H4COO)SnMe3](2)(4,4-bipy) 13, have been synthesized. The coordination behavior of 4-sulfanylbenzoic acid is monodentate in 1-8 by thiol S atom but not carboxylic oxygen atom. While, in 9-13 it behaves as multidenate by both thiol S atom and carboxylic oxygen atoms. The supramolecular structures of 6, 11 and 13 have been found to consist of 1D molecular chains built up by intermolecular O-H center dot center dot center dot O, C-H center dot center dot center dot O or C-H center dot center dot center dot S hydrogen bonds. The supramolecular aggregation of 7 is 2D network determined by two C-H center dot center dot center dot O hydrogen bonds. Extended intermolecular C-H center dot center dot center dot O interactions in the crystal lattice of 9 link the molecules into a 2D network. (c) 2005 Elsevier B.V. All rights reserved.
