Crystal Structure Of a 2D Cadmium(II) Coordination Polymer Containing a Flexible bis(imidazole) Ligand

Abstract

A new coordination polymer {[Cd(mbix)(nip)·H₂O]·0.25H₂O}n (mbix = 1,3-bis(imidazol-1-ylmethyl)benzene, H₂nip = 5-nitroisophthalic acid) is hydrothermally synthesized and characterized by elemental analysis, IR spectroscopy, and single crystal X-ray diffraction. The complex crystallizes in the monoclinic system, space group P2₁/c, a = 10.328(1) Å, b = 26.683(3) Å, c = 8.6612(8) Å, β = 107.462(1)°, V = 2276.9(4) ų, Z = 4, D_c = 1.699 g/cm³, μ = 1.015 mm⁻¹, F(000) = 1170, the final R = 0.0469 and wR = 0.0833. The complex exhibits a 2D (4,4) grid with point symbol 4⁴.6². The thermogravimetric curve of the complex was addressed.
