摘要：
The title complex {[Co(dimb)(2)(H2O)(2)]center dot(NO3)(2)center dot(H2O)(2)}(n) (1) (dimb = 1, 3-di(imidazol-1-ylmethyl)-5-methylbenzene) has been hydrothermally synthesized by the reaction of dimb with Co(NO3)(2)center dot 6H(2)O in aqueous solution. The cobalt(II) atoms are linked by bridging dimb ligands to form 2D corrugated and wavy networks containing Co-4(dimb)(4) macrocyclic motifs. Two neighboring independent layers interlinked each other in a parallel fashion to construct three-dimensional structure by O-H center dot center dot center dot O, N-H center dot center dot center dot O and C-H center dot center dot center dot O hydrogen bonds. Magnetic measurement shows the weak antiferromagnetic interaction with a one-dimensional chain model in the range of 5-300 K, with J of -0.68 cm(-1).
