Crystals of the title compound, [Cu(C6H15N3O3)(2)]Cl-2.-4H(2)O, are is
otypic with those of the analogous Cu-II bromide and the corresponding
Ni-II and Zn-II bromides [Hegetschweiler et al. (1992). Inorg. Chem.
31, 2341-2346]. The coordination polyhedron of the Cu atom shows a str
ong Jahn-Teller distortion from octahedral symmetry. The location of a
ll H-atom positions gives a more detailed understanding of the three-d
imensional hydrogen-bonding framework in (I) and its related compounds
