摘要Two new metal-organic complexes ,{[Co2(bptc)(DPPZ)2(H2O)2]·H2O}n 1 and {[Co2(ccm)2(DPPZ)2]·H2O}n 2, were obtained by the hydrothermal reactions of Co(NO3)2·6H2O with chelating ligand dipyrido[3,2-a:2'3'-c]phenazine (DPPZ) and the corresponding carboxylic acid, namely, 3,3'4,4'-benzophenonetetracarboxylic acid (H4bptc) or 2-carboxycinnamic acid (H2ccm), respectively. The complexes were structurally characterized by single-crystal X-ray diffraction, elemental analyses, IR spectra, and thermal gravimetry. 1 presents unique chiral chain structures, which are further consolidated into three-dimensional supramolecular frameworks via noncovalent bonds, such as hydrogen bonding and π-π interactions. 2 features infinite double-chain structures, which are connected by strong π-π interactions to result in three-dimensional supramolecular architectures.
