Study on Crystal Structure and Interaction with Biologic Molecule of Bis[tri(hydroxymethyl)methylglycine] Ni(II) Complex

Abstract

A single crystal of complex [Ni(tricine)₂]•6H₂O was synthesized, where tricine is tri(hydroxy- methyl)methylglycine. The crystal belongs to monoclinic system, P2(1)/n space group. One nitrogen atom and two oxygen atoms of the tri(hydroxymethyl)methylglycine coordinate to nickel(II). The Ni(II) presents an octahedral geometry. Two dimensional structure of the complex is formed by intermolecular hydrogen bonds. The interaction of complex with fish sperm, ATP and ade is studied by UV spectrum, and their interacion mechanism is also primary analyzed.

Key words: tri(hydroxymethyl)methylglycine, Ni(II), complex, structure, biologic molecule
