The title compound, [Cu-2(C8H4O4)(C12H8N2)(4)](ClO4)(2), was prepared from
the hydrothermal reaction of CuCl2, 1,4-dicyanobenzene, 1,10-phenanthroline
and water at 443 K. The compound is a dimer in which the cation lies about
an inversion center. The terephthalate moiety acts as a bridging ligand an
d the phenanthrolines as terminal ligands. The unique Cu atom is coordinate
d by two O and four N atoms in a distorted octahedral geometry, with Cu-O d
istances of 1.955 (2) and 2.815 (2) Angstrom, and Cu-N distances of 2.008 (
2) to 2.216 (2) Angstrom.
