title: Aqua[N-(6-carboxylato-kappa O-pyridine-2-carbonyl-kappa N)-L-histidinato-kappa(2)N,N']copper(II).
abstract: The title compound, [Cu(C(13)H(10)N(4)O(5))(H(2)O)], is an asymmetric and pentacoordinated square-pyramidal copper(II) complex, with a water molecule occupying an apical position. It consists of syn and anti isomers of the apical water molecule with respect to the metal-free carboxyl group on the equatorial ligand. The crystal structure of this complex is a rare example of conformational isomerization, in which the two isomers cocrystallize in a 1:3 ratio of syn to anti molecules in the same lattice.
