| Abstract |
Crystallography reveals that the title compound, nBu(3)SnL(LH) features a neutral nBu(3)SnL species complexed to the neutral form of the carboxylic acid, where LH is 2-[(E)-2-(4-hydroxy-3-methylphenyl)diazen-1-yl]benzoic acid. The resulting trigonal bipyramidal coordination geometry is based on a trans-C3O2 donor set; O-Sn-O = 167.59(13)degrees. As such, a new structural motif is found for triorganotin carboxylates. In the crystal structure, two nBu(3)SnL(LH) molecules self assemble via O-HO hydrogen bonding leading to the formation of 48-membered macrocyclic rings.
