Abstract

The synthesis, crystal structures and spectroscopy of [{Cu(mu(2)-adip)(benzim)(2)(H2O)}(n)] (1), [{Cu(mu(2)-adip)(4-pyme)(2)(H2O)}(n)] (2), [{Cu(mu(3)-adip)(nia)(2)}(n)center dot nH(2)O] (3), [{Cu(mu(2)-adip)(pydca)(2)}(n)] (4) and [{Cu(mu(4)-adip)(mna)}(n)center dot nH(2)O] (5) (adip = adipate(2-) anion, benzim = benzimidazole, 4-pyme = 4-pyridylmethanol, nia = nicotinamide, pydca = 3,4-pyridinedicarboxamide, mna = N-methylnicotinamide) are reported. The complexes under study were characterized by electronic, IR and EPR spectroscopy, and single-crystal X-ray structure analysis. The complexes form one-dimensional or two-dimensional brick-wall like coordination polymers. The coordination environments around the copper atoms of complexes 1-3 and 5 are distorted tetragonal pyramidal. The copper atom in complex 4 has tetragonal-bipyramidal coordination. Four different coordination modes of adipate ligands in the studied copper(II) complexes were observed. The coordination polymers of the complexes are connected through hydrogen bonds into 2-D or 3-D supramolecular frameworks.
