Hydrothermal reactions of 1,2,4-benzenetricarboxylic acid, 1,10-phenanthroline and transition metal cations including Zn-II or Co-II, in basified aqueous solution gave rise to two complexes, [Zn-3(btrc)(2)(1,10-phen)(2)(H2O)(2)](n) (1), and [CO3(btrc)(2)(1,10-phen)(2)(H2O)(2)](n) (2) (hire = 1,2,4-benzenetricarboxylate, and 1,10-phen = 1,10-phenanthroline). 1 2 crystalize isotypically in the tri-clinic space group P (1) over bar. The btrc ligand acts as multi-dentate bridging ligand in both compound I and 2 to link up transition metal atoms into lamella networks, which are further attached into three-dimensional frameworks through complex hydrogen bonding and pi-pi interactions. The photoluminescence spectrum for compound 1 has also been studied. The corresponding reaction with Cu2+ follows another pathway.
