The copper(Ⅱ)-phytate-terpyridine ternary system: the first crystal structures showing the interaction of phytate with bivalent metal and ammonium cations

摘要

Phytate, an abundant molecule in eukaryotic cells, interacts strongly with inorganic cations and polyamines. This interaction is essential for determining the possible functions of this biomolecule. We present here the first solution and crystallographic study of the formation of phytate complexes in the Cu(Ⅱ)-phytate-terpy and phytate-terpy (terpy = 2,2':6',2"-terpyridine) systems.
