摘要
The syntheses, structures and thermal properties of three coordination networks [Zn(L 1 )(1,4-BDC)]·H 2 O (L 1 = N,N′-di(4-pyridyl)adipoamide; 1,4-H 2 BDC = 1,4- benzenedicarboxylic acid), 1, [Cd(L 1 )(1,4-BDC)]·2H 2 O, 2, and [Zn 2 (L 2 )(1,4-BDC) 2 ]·2CH 3 OH (L 2 = N,N′-di(4-pyridyl) dodecanamide), 3, are reported. Complexes 1 and 2 show the dia topology with the rare 8- and 9-fold interpenetrating modes, respectively, while 3 exhibits an interpenetrating 3-fold framework with the pcu Zn 2 (COO) 2 dimer decorated topology. Complex 2 shows the maximum number of interpenetration presently known for interpenetrating diamondoid networks of coordination networks containing mixed spacer ligands.
