Crystals of {[Cd(oba)(4-pna)]center dot 0.25H(2)O}(n) (1, oba = oxybisbenzoate, 4-pna = 4-Pyridylnicotinamide) were prepared by hydrothermal methods. A single-crystal structure determination showed the presence of two-fold interpenetrated [Cd-2(oba)(2)](n) dimer-based (4,4) layers, featuring embedded {Cd2O2} dimers that serve as 4-connected nodes. In turn these layers are connected by the dipodal 4-pna ligands into a [Cd(oba)(4-pna)](n) 3-D coordination polymer network. Including these connections, the {Cd2O2} dimers can be considered as 8-connected nodes; these build a new but simple self-penetrated network with a 42464 topology substantially different from a standard body centered cubic bat net. Luminescent and thermal properties of 1 are also reported.
