A 2D Cobalt(Ⅱ) Coordination Polymer [Co(iqnc)2]n: Synthesis, Crystal Structure and Characterization

A new cobalt(Ⅱ) coordination polymer with the formula of [Co(iqnc)2]n(1, iqnc = l-isoquinolinecarboxylate) has been synthesized through hydrothermal synthesis and structurally characterized by single-crystal X-ray diffraction method. The title coordination polymer represents a two-dimensional layer structure featuring adjacent one-dimensional [Co(iqnc)2]n chains connected with each other by uncoordinated oxygen atoms of carboxylate. Crystal data: monoclinic, space group P21/c, a = 15.4302(2), b = 5.6743(7), c = 9.2307(1) ?, β = 98.459(2)o, V = 799.41(2) ?3, Z = 2, S = 1.019, the final R = 0.0346, w R = 0.0876(I > 2σ(I)) and R = 0.0477 and wR = 0.1159 for all reflections. In addition, elemental analysis, IR, and magnetism properties are presented.
