摘要: Abstract 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)]·1.5H2O}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)·3.5H2O}n (2, phdp = phenylenedipropionate), which possesses rare (3,6) 2D trigonal lattice 6-connected dimers. Changing nitrogen donor atom disposition by using 3-bpmp as co-ligand yielded [Cd(1,4-phdp)(3-bpmp)(H2O)]n (3), crystallizes in 3-fold interpenetrated achiral diamondoid lattice. [Cd(1,3-phda)(4-bpmp)]n (4) adopts very similar to that 1. Complexes 1–4 undergo blue-violet luminescence upon exposure ultraviolet radiation.
