A novel three-dimensional supramolecular framework with one-dimensional channels: synthesis and crystal structure of [Cu(DPC)(H 2O) 3] (H 2DPC=Pyridine-2,6-dicarboxylic acid)

Abstract

A new supramolecular compound formulated [Cu(DPC)(H 2O) 3] (H 2DPC=Pyridine-2,6-dicarboxylic acid) was synthesized under mild conditions and characterized by elemental analyses, IR spectrum, thermogravimetric (TG) analysis and single-crystal X-ray diffraction. The crystal crystallizes in the monoclinic system, space group of C2/ c with a=6.4448(9) Å, b=23.192(3) Å, c=6.9139(12) Å, α=90°, β=106.622(11)°, γ=90°, V=990.2(3) Å 3, Z=4, R=0.0580, and wR 2=0.1522. The compound exhibits an interesting three-dimensional (3D) supramolecular framework structure with one-dimensional channels, which is constructed by extensive hydrogen-bonding and π–π stacking interactions.
