Solvothermal reactions of 4-cyanobenzoic acid (HL1), NaN3, hydrated ZnSO4 in the presence of ancillary ligands pyrazine or 4,4'-dimethylbipyridine (Me(2)bpy) afforded a 3-D coordination polymer [Zn(L-2)(H2O)](n) (1) and a 2-D layer [Zn-3(Me(2)bpy)(N-3)(2)(L-2)](n) (2) (L-2 = 4-tetrazolylbenzenecarboxylate), respectively in which pyrazine significantly alters the self-assembly of 1 and the coordination of Me(2)bpy in 2 leads to a novel linearly trinuclear [Zn-3(Me(2)bpy)(2)(N-3)(2)](4+) subunit functioning as a secondary building block (SUB). Their crystal structures have been determined by X-ray crystallography and solid state luminescent properties have been measured at room temperature.
