摘要: 由对羧甲氧基肉桂酸(H2CMOPAA)合成了2个锌(Ⅱ)/镉(Ⅱ)配合物[Zn(CMOPAA)(Phen)(H2O)]n1)和[Cd(CMOPAA)(Phen)]n2)(Phen=菲咯啉)。通过元素分析、红外光谱、热重和X射线单晶衍射表征了其结构。配合物1属单斜晶系,P21/n空间群,晶胞参数为a=0.698 84(8)nm,b=1.751 16(19)nm,c=1.655 49(18)nm,β=95.165(10)°,V=2.017 7(4)nm3。配合物1的不对称单元中有1个Zn2+、1个CMOPAA2-、1个Phen和1个配位水分子。Zn(Ⅱ)离子是六配位的扭曲八面体构型,CMOPAA2-的羧基连接相邻的Zn(Ⅱ)形成了一条螺旋形的一维链。分子间氢键连接上下的一维链形成了一个二维氢键网络结构。配合物2属三斜晶系,P1空间群,晶胞参数为a=0.988 28(16)nm,b=1.040 08(17)nm,c=1.096 15(18)nm,α=72.213(2)°,β=74.439(2)°,γ=71.265(2)°,V=0.997 8(3)nm3。配合物2的不对称单元中有1个Cd2+、1个CMOPAA2-和1个Phen。Cd(Ⅱ)离子是七配位的扭曲单帽三角棱柱体构型,CMOPAA2-的羧基连接相邻的4个Cd(Ⅱ)形成了一个平行四边形的26元大环结构,CMOPAA2-的羧基连接相邻的平行四边形结构形成了一条一维带状结构。研究了配合物12的热稳定性和抑菌活性。

Abstract: Two Zn(Ⅱ)/Cd(Ⅱ) complexes, [Zn(CMOPAA)(Phen)(H2O)]n (1) and [Cd(CMOPAA)(Phen)]n (2), (H2CMOPAA =4-carboxymethoxy-3-phenylpropenoate and Phen=1,10-phenanthroline) were synthesized with H2CMOPAA ligand by solvothermal condition and structurally characterized by element analysis, IR, TGA (thermogravimetric analysis) and single crystal X-ray diffraction. Complex 1 crystalizes in the monoclinic system, space group P21/n with a= 0.698 84(8) nm, b=1.751 16(19) nm, c=1.655 49(18) nm, β=95.165(10)°, V=2.017 7(4) nm3. The asymmetric unit of complex 1 consists of one Zn(Ⅱ) ion, one CMOPAA2- ligand, one Phen ligand and one coordinated H2O. Zn(Ⅱ) ion is a six-coordinated distorted octahedral configuration. The carboxyl group of CMOPAA2- ligand connects the adjacent zinc ions to form a helical one-dimensional chain. Hydrogen bonds link the adjacent one-dimensional chains to form a two-dimensional network. Complex 2 crystalizes in the triclinic system, space group P1 with a=0.988 28(16) nm, b =1.040 08(17) nm, c=1.096 15(18) nm, α=72.213(2)°, β=74.439(2)°, γ=71.265(2)°, V=0.997 8(3) nm3. The asymmetric unit of complex 2 consists of one Cd(Ⅱ) ion, one CMOPAA2- ligand and one Phen ligand. Cd(Ⅱ) ion is a seven-coordinated twisted single-cap triangular prism configuration. The carboxyl group of CMOPAA2- ligand connects the adjacent cadmium ions to form a parallelogram 26-membered large ring structure. The 26-membered large rings are linked to a one-dimensional band-like structure. The thermal stabilities and antibacterial activities of complexes 1 and 2 were studied.
