S 3–zinc(II) complexes

The bridged μ-hydroxo zinc(II) complex [TtiZn(μOH)ZnTti]ClO 4 ( 2) cleaves the P–O bond in tris( p-nitrophenyl)phosphate, affording a mixture of the monomeric phosphate diester complex TtiZn–OP(O)(OC 6H 4- p-NO 2) 2 ( 3) and phenoxide complex TtiZn–OC 6H 4- p-NO 2 ( 4). The coordination geometry in both complexes is best described as distorted tetrahedral with an S 3O ligand donor set. The bridged μ-hydroxo dinuclear four-co-ordinated zinc(II) complex 2, derived from hydrotris( N-xylyl-2-thioimidazolyl)borate cleaves the P–O bond in tris( p-nitrophenyl)phosphate to form a mixture of a monomeric phosphate diester complex 3 and phenoxo complex 4.
