本文合成了2种含有吡啶甲酸根的三(2-苯并咪唑亚甲基)胺合锰配合物.并对其进行了红外.元素分析和X.射线单晶衍射测定.结果表明,单核配合物1和2分别具有三角双锥和扭曲八面体的几何构型.在配合物1中,烟酸根阴离子利用一个羧基氧原子和锰离子配位;在配合物2中,邻吡啶甲酸根阴离子采取N.O螯合的配位方式.由于烟酸根和邻吡啶甲酸根的配位方式不同,导致配合物晶体结构中存在不同类型的氢键.配合物1形成了由氢键连接的二维网状结构,而配合物2只能形成由氢键连接成的一维链状结构.

Two complexes[Mn(ntb)(nic)]ClO_4·H_2O(1)and[Mn(ntb)(pic)]ClO_4·CH3OH·2H_2O(2)have been prepared and structurally characterized,where ntb is tris(2-benzimidazolylmethyl)amine,nic is anion of nicotinic acid and pic is anion of picolinic acid.X-ray analysis indicates that complexes 1 and 2 are both mononuclear and the Mn(Ⅱ)centeradopts trigonal-bipyramidal and distorted octahedral coordination geometry,respectively.In complex 1,the nic anioncoordinates with Mn(Ⅱ)ion through one of carboxylate oxygen atoms.In complex 2,the pic anion coordinates with Mn(Ⅱ)ion in bidentate N,O-chelating mode.Furthermore,complex 1 reveals 1D,2D dimensional structures based on intermolecular hydrogen-bonding interactions.Complex 2 has 1D chain through intra-,intermolecular hydrogenbonding interaction.Crystal data：[Mn(ntb)(nic)]ClO_4·H_2O(1),M_r=701.99 g·mol~(-1),Triclinic,P1,a=1.00247(13)nm, b=1.25640(15)nm,c=1.303 33(13)nm,α=83.470(8)°,β=78.701(9)°,γ=76.701(10)°,V=1.562 5(3)nm~3,Z=2,R_1=0.0705,wR_2=0.1338[I>2σ(I)]；[Mn(ntb)(pic)]ClO_4·CH_3OH·2H_2O(2),Mr=752.04 g·mol~(-1),Triclinic,P1,α=1.025 90(13)nm,b=1.296 70(16)nm,c=1.454 82(17)nm,a=72.525(7)°,β=72.041(6)°,γ=69.880(6)°,V=1.6873(4)nm~3,Z=2,R_1=0.040 1,wR_2=0.0952[I>2σ(I).
