摘要：

We have synthesized and structurally characterized the first anionic phosphates undergoing sulfur donor action in the presence of hydrogen bonding. As a consequence, these phosphates increase their coordination geometry toward a trigonal bipyramid. It is suggested that such action may occur at active sites of phosphoryl transfer enzyme containing anionic phosphate substrates.
