摘要

标题化合物[Co(C7H4O2I)2(C10H14N2O)2(H2O)2]是一种二维氢键超分子配合物。该配合物在三斜空间群P1中结晶,单位胞参数为a = 7.2964(13), b = 8.6047(17), c = 16.745(3) a, α = 93.034(15), β = 101.574(15), γ = 111.975(14)°,Z = 1。Co(II)离子位于对称中心,处于由两个吡啶N原子、两个羧酸O原子和两个来自水分子的O原子组成的八面体配位环境中。分子间的C-H…O和O- h…O氢键形成R22(16)、R22(18)和R22(20)环,形成一维聚合物链。C-H…O和O- h…O氢键、π-π和C-H…π相互作用的广泛二维网络是晶体稳定的原因。

Synthesis and Crystal Structure of Diaquabis(4-iodinebenzoato-κO)bis-(nicotinamide-κN)cobalt(II)
The title compound [Co(C7H4O2I)2(C10H14N2O)2(H2O)2] is a two-dimensional hydrogen-bonded supramolecular complex. The complex crystallizes in the triclinic space group P1 with unit-cell parameters a = 7.2964(13), b = 8.6047(17), c = 16.745(3)A, α = 93.034(15), β = 101.574(15), γ = 111.975(14)° and Z = 1. The Co(II) ion resides on a centre of symmetry, and is in an octahedral coordination environment comprising two pyridyl N atoms, two carboxylate O atoms and two O atoms from water molecules. Intermolecular C-H…O and O-H…O hydrogen bonds produce R22(16), R22(18) and R22(20) rings, which lead to one-dimensional polymeric chains. An extensive two-dimensional network of C-H…O and O-H…O hydrogen bonds, π-π and C-H…π interactions are responsible for crystal stabilization.
