Interactions of metal ions with nucleotides. Metal bonding to N(7) in the ternary copper(II)–inosine 5′-phosphate complex [Cu(5′-IMP)(2,2′-bipyridyl)(H2O)2]·NO3·H2O: X-ray crystal structure analysis, and metal bonding to both N(7) and phosphate in the binary complex [Cu(5′-IMP)]·H2O: X-ray characterization

Abstract

X-Ray crystal structure analysis of the ternary complex [Cu(inosine 5′-phosphate)(2,2′-bipyridyl)(H₂O)₂]·NO₃·H₂O and single-crystal X-Ray characterization of the binary complex [Cu(inosine 5′-phosphate)]·H₂O show the former to be monomeric with the square-pyramidal copper ion directly bonded to N(7) of the base, to the bidentate bipyridyl ligand, and to two water molecules, and the latter to be isostructural with the previously reported zinc analogue, forming a two-dimensional polymer with the tetrahedral copper ion directly bonded to N(7) and to three phosphate oxygen atoms.
