合成了2个含肟基Schiff碱Co(Ⅱ)和Cu(Ⅱ)配合物Co(L~1)_2(1)和Cu(L~2)_2(2)。X射线单晶衍射分析结果表明,配合物1和2具有相似的结构,均由1个中心金属离子和2个双齿配体单元组成,且金属离子的配位数为4,具有平面四边形结构。配合物1和2均属于三斜晶系,空间群均为P1。配合物1的晶胞参数为a=1.156 40(11)nm,b=1.376 81(12)nm,c=1.388 59(13)nm,α=63.776 0(10)°,β=87.400(2)°,γ=84.280(2)°;配合物2的晶胞参数为a=1.156 42(9)nm,b=1.372 19(13)nm,c=1.404 40(12)nm,α=63.683 0(10)°,β=87.227(2)°,γ=84.883 0(10)°。2个配合物分子均通过分子间C-H…O和C-H…π氢键作用以及分子间π…π堆积作用相连接,形成了二维层状超分子结构。
Two Cu (Ⅱ) complexes Co (L ~ 1) _2 (1) and Cu (L ~ 2) _2 (2) were synthesized. X-ray single crystal diffraction analysis results show that the complexes 1 and 2 have a similar structure, each composed of one central metal ion and two bidentate ligand units, and the metal ion has a coordination number of 4 and has a planar tetragonal structure . Complex 1 and 2 belong to the triclinic system, space group are P1. The unit cell parameters of complex 1 were a = 1.156 40 (11) nm, b = 1.376 81 (12) nm, c = 1.388 59 (13) nm, °, γ = 84.280 (2) °. The lattice parameters of complex 2 were a = 1.156 42 (9) nm, b = 1.372 19 (13) nm, c = 1.404 40 10) °, β = 87.227 (2) °, γ = 84.883 0 (10) °. Two complex molecules are connected by C-H ... O and C-H ... π hydrogen bonds and intermolecular π ... π stacking, forming a two-dimensional layered supramolecular structure.
