interactions of mononuclear Cu(II) complexes in which one H2O, two pyridines (py), and two p-substituted benzoate (p-RBA) ligands (R = F, Cl, Br, I, CH3, and OCH3) were coordinated to a Cu(II) ion, forming a penta-coordinated asymmetric [Cu(II)(p-RBA)2(py)2(H2O)] mononuclear structure with a permanent dipole moment along the direction of the Cu–OH2 coordination axis. Each asymmetric [Cu(II)(p-RBA)2(py)2(H2O)]
通过调节单核Cu(II)配合物的分子间相互作用来设计具有二次谐波生成(SHG)的极性晶体,其中一个H 2 O,两个吡啶(py)和两个对位取代的苯甲酸酯(p -RBA)配体(R = F,Cl,Br,I,CH 3和OCH 3)与Cu(II)离子配位,形成五配位不对称[Cu(II)(p -RBA)2(py)2( H 2 O)]沿Cu–OH 2配位轴方向具有永久偶极矩的单核结构。每个不对称[Cu(II)(p -RBA)2(py)2(H 2 O)]络合物形成极性一维氢键链,[Cu(II)(p -RBA)2(py)2(H 2 O)p -RBA配体的非配位羧酸氧原子与H 2 O分子的氢原子之间存在] ∞。极性晶体的形成取决于极性氢键链的排列。每个极性链的平行排列产生极性晶体。p中R基团的化学设计-RBA配体能够调节链间相互作用的大小和晶体极性;使用具有R = Cl,Br,I和OCH 3的p -RBA配体
