The structure of bis[4-amino-1-methyl-2(1H)-pyrimidinone] dichlorocopp
er(II) consists of discrete [CuCl2-(C5H7N3O)(2)] units. The coordinati
on about the Cu-II ion is distorted 4 + 2 octahedral. The non-equivale
nt 1-methylcytosine ligands are bonded to the metal through N(3) and m
ore weakly through O(2). The average N-Cu-Cl trans angle is 159.9(1)de
grees.
