Coordination Patterns of the Diphosphate in IDP Coordination Complexes: Crystal Structure and Chirality.

The knowledge of accurate geometrical parameters from X-ray diffraction studies in the solid state of metal nucleotide is very important for understanding the relationship between structures and properties, including biochemical processes and even enzyme-metal-substrate interactions. The research is also very necessary to precisely and controllably design the functional materials. Here, seven types of coordination polymers of inosine 5'-diphosphate nucleotide (IDP) with transition metals, {[Zn(HIDP)(azpy)(HO)]·4HO} (), {[Cd(IDP)(bpda)]·[Cd(HO)]·11HO} (), {[Cd(IDP)(4,4'-bipy)(HO)]·6HO} (), {[Cd(IDP)(bpe)(HO)]·(Hbpe)·26HO} (), {[Cu(IDP)(azpy)(HO)]·5HO} (), {[Cu(IDP)(bpe)(HO)]·9HO} (), and {[Co(HIDP)(azpy)(HO)]·7HO} () [4,4'-bipy = 4,4'-bipyridine, azpy = 4,4'-azopyridine, bpe = 1,2-bis(4-pyridyl)ethene, and bpda = 1,4-bis(4-pyridyl)-2,3-diaza-1,3-butadiene], were designed, synthesized, and firmly characterized using single-crystal X-ray diffraction.
