摘要

Employing the multicarboxylate and N-donor mixed ligands to react with Zn(NO3)(2)center dot 6H(2)O affords a new 3D compound [Zn-3(HBPTC)(2)(bmp)(2)(H2O)(2)]center dot 2H(2)O (1) (H4BPTC = biphenyl-3,3',4,4'-tetracarboxylic acid, bmp = 3,6-bis(imidazol-1-yl)pyridazine). Structural analyses show that compound 1 possesses a (4,4)-connected neutral framework bearing rare NbO-x-d subnets, and it represents the first replica of the theoretically predicted NbO-x-d/Im-3m -> Imm2 topology net. Moreover, compound 1 can demonstrate the interesting reversible structural transformation property induced by water molecules. Additionally, thermal stability and luminescence properties of 1 were investigated.
