Synthesis and Crystal Structure of a 3D Cd(II) Coordination Polymer Assembled with Itaconate and 1,2-Bis(4-pyridyl)ethane

Abstract

The three-dimensional cadmium coordination polymer {[Cd4(H2O)2(ita)4(bpe)6]⋅(H2O)26}n (1) (ita = itaconate; bpe = 1,2-bis(4-pyridyl)ethane) was obtained by self-assembly solution reaction under ambient conditions and characterized by elemental analysis, IR spectroscopy, and X-ray single crystal diffraction. Compound 1 crystallizes in the orthorhombic system with space group P212121. Cd centers exhibit distorted octahedral and distorted pentagonal bipyramidal coordination geometries. Polymer 1 demonstrates a new 3D topology.
