The reaction of CuII acetate with the new sulfo-functionalized arylhydrazone of β-diketone 2-[2-(4,4-dimethyl-2,6-dioxocyclohexylidene)hydrazinyl]benzenesulfonic acid (H2L, 1) in aqueous methanol solution led to the formation of the 2D coordination polymer [Cu4(1κ2O,κN:2κO,κN-L)4(μ-OH2)2]·H2O}n (2). However, when the reaction was peformed in the presence of the N-containing species cyanoguanidine
CuII 乙酸盐与 β-二酮 2-[2-(4,4-二甲基-2,6-二氧代环己基)肼基]苯磺酸 (H2L, 1) 的新型磺基官能化芳腙在甲醇水溶液中的反应导致形成二维配位聚合物[Cu4(1κ2O,κN:2κO,κN-L)4(μ-OH2)2]·H2O}n (2)。然而,当反应在含氮物质氰基胍 (cyg)、3,5-二甲基-1H-吡唑 (dp)、2,2'-联吡啶 (bpy) 或吡嗪 (py) 存在下进行时,单核 (H3O+)2[Cu(κ2O,κN-L)2] (4), [Cu(κ2O,κN-L)(dp)2] (3) 或 [Cu(κ2O,κN-L)(κ2N- bpy)] (5) 或双核 [Cu(κ2O,κN-L)(H2O)}2(κ-py)]·CH3OH (6) 复合物。通过元素分析、红外光谱、单晶 X 射线衍射分析和 1 H 和 13 C NMR 光谱对化合物进行表征。
