Abstract
Abstract Twelve new organotin complexes with 4-sulfanylbenzoic acid of two types: R n Sn[S(C 6 H 4 COOH)] 4− n ( I ) ( n = 3: R = Me 1 , n -Bu 2 , Ph 3 ; PhCH 2 4 ; n = 2: R = Me 5 ; n -Bu 6 , Ph 7 , PhCH 2 8 ) and R 3 Sn(SC 6 H 4 COO)SnR 3 · mEtOH ( II ) ( m = 0: R = Me 9 , n -Bu 10 , PhCH 2 12 ; m = 2: R = Ph 11 ), along with the 4,4′-bipy adduct of 9 , [Me 3 Sn(SC 6 H 4 COO)SnMe 3 ] 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⋯O, C–H⋯O or C–H⋯S hydrogen bonds. The supramolecular aggregation of 7 is 2D network determined by two C–H⋯O hydrogen bonds. Extended intermolecular C–H⋯O interactions in the crystal lattice of 9 link the molecules into a 2D network.
