{[Mn(mes)(dmb)(H₂O)] ⋅ H₂O}_n (1) and [Mn(mes)(bpy)]_n (2); (mes=mesaconato; dmb=5,5’-dimethyl-2,2’-bipyridine; bpy=2,2’-bipyridine), were obtained by self-assembly solution reaction at ambient conditions, and structurally characterized by single crystal X-ray diffraction. 1 crystallizes in an orthorhombic system with a Pbca space group and forms a one-dimensional (1D) coordination polymer; the six-coordinated Mn(II) centers display a distorted-trigonal prismatic configuration. 2 crystallizes in an orthorhombic system with a P2₁2₁2 space group yielding a two-dimensional (2D) coordination array, their metal centers having a distorted octahedral geometry. Magnetic susceptibility measurements reveal that 1 is paramagnetic, while 2 shows weak antiferromagnetic coupling.

辅助配体对中空桥联锰配位聚合物晶体结构和磁性能的影响

{[Mn(mes)(dmb)(H ₂ O)]·H ₂ O} _n ( 1 ) 和 [Mn(mes)(bpy)] _n ( 2 ); （mes=mesaconato；dmb=5,5'-二甲基-2,2'-联吡啶；bpy=2,2'-联吡啶），在环境条件下通过自组装溶液反应获得，并通过单晶X进行结构表征射线衍射。1在具有Pbca空间群的斜方晶系中结晶并形成一维（1D）配位聚合物；六配位 Mn(II) 中心显示出扭曲的三角棱柱构型。2在具有P2 ₁ 2 ₁ 2空间群的斜方晶系中结晶，产生二维 (2D) 配位阵列，其金属中心具有扭曲的八面体几何形状。磁化率测量表明1是顺磁性的，而2 则显示弱反铁磁性耦合。
