4′‐obb2− ligands, of which two function as monodentate ligands and the other as a bidentate ligand, and by two N atoms from bridging 4,4′‐bipy ligands, thereby forming a distorted octahedral CoN2O4 coordination geometry. Adjacent crystallographically equivalent CoII ions are bridged by the O atoms of 3,4′‐obb2− ligands, affording an eight‐membered Co2O4C2 ring which is further extended into a two‐dimensional
一种新的配位聚合物(CP),即聚[(μ-4,4'-联吡啶)(μ 3 -3,4'- oxydibenzoato)钴(II)],[CO(C 14 H ^ 8 ø 5)(C通过自组装Co(NO 3)2 ·6H 2制备10 H 8 N 2)] n或[Co(3,4'-obb)(4,4'-bipy)] n(1)O与很少使用的3,4'-氧二苯甲酸(3,4'-obbH 2)配体和4,4'-联吡啶(4,4'-联吡啶)在溶剂热条件下进行结构分析,并通过元素分析,红外光谱,单晶X射线晶体学和粉末X射线衍射(PXRD)进行了表征。X射线单晶衍射显示,每个Co II离子与来自三个3,4'-obb 2-配体的四个O原子六配位,其中两个用作单齿配体,另一个用作双齿配体,通过桥接4,4'-bipy配体形成两个N原子,从而形成扭曲的八面体CoN 2 O 4配位几何形状。相邻的晶体等效的Co II离子被3,4'-obb 2-配体的O原子桥接,提供了八元的Co2
