Abstract: | Two new coordination polymers, Zn(bix)0.5(glu)]n (1) and {Co(bix)(glu)]·4H2O}n (2), were synthesized (bix = 1,4-bis(2-methylimidazol-1-ylmethyl)benzene, glu = glutarate). In 1, each Zn(II) is connected by four glu ligands and extend to form a Zn(glu)]n 2-D network. Adjacent Zn(glu)]n 2-D networks are bridged by bix ligands to construct a 6-connected 3-D network based on the Zn2 unit. 2 shows an undulated 2-D (4,4) network. The interesting structural feature of 2 is that there are 1-D water chains. The O–H···O hydrogen bond interactions link the 2-D coordination networks and construct the 3-D supramolecular architecture in 2. The glu ligands are bis-(bidentate) bridges in 1 and bis-(monodentate) bridges in 2. The luminescence of 1 and thermal stability of 1 and 2 were investigated. |
