Bis(β-diketonato) Co(II) complex, [Co(dbm)2] (dbm = dibenzoylmethanato or 1,3-diphenyl-propane-1,3-dionato), was examined as a linear building block for the construction of coordination polymers in the combination with a potentially tridentate ligand, 2,6-bis(4′-pyridyl)-4-(3′-pyridyl)pyridine (L1). L1 was expected to work as a conformationally flexible ligand because of the rotation of the terminal
Bis(β-diketonato) Co(II) 复合物 [Co(dbm)2](dbm = dibenzoylmethanato 或 1,3-diphenyl-propane-1,3-dionato)作为线性结构单元用于构建配位聚合物与潜在的三齿配体,2,6-双(4'-吡啶基)-4-(3'-吡啶基)吡啶(L1)组合。由于末端 3-吡啶基部分的旋转,L1 有望用作构象灵活的配体。从甲醇-硝基苯-苄腈混合溶液中获得具有四重互穿 β-氢醌骨架的多孔配位聚合物 [Co(dbm)2]3/2(L1)·(G)(Co-1,G = 客体分子)含有 [Co(dbm)2(H2O)2] 和 L1 的溶液。单晶 X 射线衍射分析表明 Co-1 在具有晶胞参数的三角空间群 R-3 中结晶,a = b = 53.8629(12), c = 14.0649(7) Å,V = 35338(3 ) Å3。热重分析和元素分析表
