摘要：

Hydrothermal synthesis has afforded divalent cadmium coordination polymers containing bis(pyridylmethyl) piperazine (bpmp) tethers and either phenylenediacetate (phda) or phenylenedipropionate (phdp) ligands. {[Cd(1,4-phda)(4-bpmp)]center dot 1.5H(2)O}(n) (1) displays a (4,4)-grid layered structure based on 4-connected {Cd2O2} dimeric units. Extension of the pendant arms generated {[Cd(1,4-phdp)(H4-bpmp)](ClO4)center dot 3.5H(2)O}(n) (2, phdp = phenylenedipropionate), which possesses a rare (3,6) 2D trigonal lattice based on 6-connected {Cd2O2} dimers. Changing the nitrogen donor atom disposition by using 3-bpmp as the nitrogen co-ligand yielded [Cd(1,4-phdp)(3-bpmp)(H2O)](n) (3), which crystallizes in a 3-fold interpenetrated achiral diamondoid lattice. [Cd(1,3-phda)(4-bpmp)](n) (4) adopts a very similar structure to that of 1. Complexes 1-4 undergo blue-violet luminescence upon exposure to ultraviolet radiation. (C) 2009 Elsevier B.V.
