Abstract
Reaction of n-chloro-2-hydroxypyridine and pyrazine with Cu(ClO4)2ꞏ6H2O in aqueous alcohols yielded three types of products: [Cu(3-Cl-2-pyone)4(H2O)2](ClO4)2 (1); [Cu(4-Cl-2-pyone)4(pz)](ClO4)2 (2) and [Cu(5-Cl-2-pyone)4(pz)](ClO4)2 (3); and [Cu(5-Cl-2-pyone)2(H2O)2(pz)](ClO4)2 (4) and [Cu(6-Cl-2-pyone)2(H2O)2(pz)](ClO4)2 (5) [n-Cl-2-pyone = n-chloro-2-pyridone]. The structures fall into the crystal systems of monoclinic [P2/n (1), P21/n (2, 5), C2/c (4)] or orthorhombic [Pnnm, 3]. In all cases, the pyridone ligands are κ-O coordinated with ancillary pyrazine and/or water ligands also coordinated to the Cu ions. The perchlorate ions remain uncoordinated in all complexes.
