Four new complexes have been synthesized by solvothermal reactions of an imidazole-containing ligand 3,3′,5,5′-tetra(1H-imidazol-1-yl)-1,1′-biphenyl (L) with corresponding metal salts via the alternation of auxiliary multicarboxylates, [Zn2(L)(2,6-NDC)(OAc)2]·2H2O (1), [Zn2(L)(BPnDC)2]·6H2O (2), [Co2(L)(OBA)2]·8H2O (3) and [Zn4(L)2(ODAC)2]·2MeCN·5H2O (4) (2,6-H2NDC = 2,6-naphthalic acid, H2BPnDC =
通过含咪唑的配体3,3',5,5'-四(1 H-咪唑-1-基)-1,1'-联苯(L)与相应的金属盐的溶剂热反应合成了四个新的配合物通过辅助多羧酸盐的交替,[Zn 2(L)(2,6-NDC)(OAc)2 ]·2H 2 O(1),[Zn 2(L)(BPnDC)2 ]·6H 2 O(2),[Co 2(L)(OBA)2 ]·8H 2 O(3)和[Zn 4(L)2(ODAC)2 ]·2MeCN·5H 2 O(4)(2,6-H 2 NDC = 2,6-萘甲酸,H 2 BPnDC = 4,4'-羰基二苯甲酸,H 2 OBA = 4,4'-氧化苯甲酸和H 4 ODAC = 3,3' ,4,4′-氧化苯四羧酸)。通过单晶和粉末X射线衍射,IR,元素和热重分析对复合物进行表征。它们全部都具有基于M(II)–L二维层的不同的三维(3D)框架,这些框架通过具有不同桥接角和配位数的辅助二羧酸酯进一步连接以获得最终的框架。复合体1是(3
