| Abstract: The reaction of 3,5-bis(pyridin-4-ylmethoxy)benzoic acid (HL) and a combination of dicarboxylic acid ligands such as thiophene-2,5-dicarboxylic acid (H2tdc), 5-hydroxybenzene-1,3-dicarboxylic acid (H3hdc), 1,4-benzenedithioacetic acid (H2bdtc) with Zn(Ⅱ) and Cd(Ⅱ) metal ions give rise to four coordination polymers with interpenetrating (3,4)-connected networks, namely, [Zn2L2(tdc)]n (1), {[Zn4L4(Hhdc)2]·H2O}n (2), {[Zn2L2(Hhdc)]·H2O}n (3), {[Cd2L2(bdtc)(H2O)]·0.5H2O}n (4). 1~3 exhibit (3,4)-connected 4-fold-interpenetrating 3D networks with point symbol of (4.82)(4.85) (1), (63)(65.8) (2) and (63)(65.8) (3) topology, respectively. 4 displays a (3,4)-connected 3-fold-interpenetrating 2D network with (63)(66) topology. Luminescent properties of 1, 3 and 4 were also investigated. CCDC: 852424, 1; 872035, 2; 887738, 3; 872037, 4. |
