| 摘 要： | 设计并成功合成了2 种新颖的以类蝎型吡唑衍生物为配体的超分子配合物Co2(HL1)2-(seb)(H2O)]·2.5H2O (1)和Cu(H2L2)(ox)]·H2Ox·MeOH (2) (H2L1=2,6-二(5-苯基-1H-吡唑-3-基)吡啶, H2seb=癸二酸, H2L2=2,6-二(5-甲基-1H-吡唑-3-基)吡啶, H2Ox=草酸), 并通过元素分析、红外光谱、紫外光谱﹑X 射线粉末衍射(PXRD)和X 射线单晶结构分析对标题配合物进行了表征. 结构分析表明, 在配合物1 和2 中, 配体H2L1 和H2L2 的配位模式不同, 其中H2L1 以μ2-η1-η1- η1-η1 模式与金属相连, 而H2L2以μ1-η1-η1-η1 的模式与金属相连; 癸二酸和草酸的配位模式也不同, 其中癸二酸作为单齿配体, 草酸作为二齿配体; 配合物1 通过C-H···O,O-H···O, N-H···O 氢键, 形成二维网络层状结构, 而配合物2 通过C-H···O, O-H···O, N-H···O氢键, 形成一维链状结构. 此外还对标题配合物的热稳定性进行了详细的分析.
