title: catena-Poly[[chlorido(1,10-phenanthro-line)copper(II)]-μ-{2-[(1S,3S)-3-acetyl-2,2-dimethyl-cyclo-but-yl]acetato}].
abstract: The title compound, [Cu(C(10)H(15)O(3))Cl(C(12)H(8)N(2))](n), is a one-dimensional coordination polymer. The Cu(II) atom is coordin-ated by a chloride ion, two N atoms from the 1,10-phenanthroline ligand, and a monodentate carboxyl-ate O atom from the pinononate anion, forming a CuN(2)ClO approximate square plane. A symmetry-generated pinononate O atom completes a square-based pyramidal geometry for the copper ion. The bridging 2-(3-acetyl-2,2-dimethyl-cyclo-but-yl)acetate anion leads to chains in the crystal propagating in [001]. Adjacent 1,10-phenanthroline rings form a dihedral angle of 39.4 (2)°.
