Phosphate triester hydrolysis promoted by S3–zinc(II) complexes with a bridged hydroxide: The crystal structure of TtiZn–OP(O)(OC6H4-p-NO2)2, Tti = hydrotris(N-xylyl-2-thioimidazolyl)borate

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.
