Two complexes, {[Cd6(o-dppd)2(μ2-Cl) 6(μ3-Cl)2(DMF)2(H 2O)2Cl2]•DMF•CH3OH} n (I) (DMF = N,N-dimethylformamide; o-dppdH = 1,3-di(pyridin-2-yl) propane-1,3-dione) and [Cu4(o-dppd)2(OAc) 4(OH)2]•4H2O (II), were synthesised and characterised by single-crystal X-ray diffraction, elemental analysis, IR, solid fluorescence and TGA. The results showed that complex I had a rodshaped polynuclear chain with hexacoordinating Cd atoms bridged by oxygen, μ2-Cl and μ3-Cl; complex II was a tetranuclear oligomer. In general, supramolecular architectures are constructed through hydrogen-bonding and π-π stacking interactions. I shows luminescence. © 2011 Institute of Chemistry, Slovak Academy of Sciences.

Two complexes, {Zn(bptc)0.5(bib)} n (I) and {Mn 2(bptc)(pip)(H2O)} n (II) (H4bptc = biphenyl-3,3′,5,5′-tetracarboxylic acid; bib = 1,4-bis(2- methylimidazol-1-yl)butane; pip = 2-phenyl-1H-imidazo[4,5-f][1,10] phenanthroline) were synthesized and characterized by single-crystal X-ray diffraction, elemental analysis, IR, TGA and solid fluorescence spectra. The results show that I and II both have 3D network architectures. I has porous architecture with a 162 topology structure. Effective porosity calculated by Platon is 5.5 %. Moreover, it has a two-fold interpenetrating structure allowed by a 70.73° torsion between the benzene rings of the bptc4- ligand and the flexibility of bib. II has a tetranuclear structure composed of binuclear architecture units with the torsion of 43.44° between the benzene rings of the bptc4- ligand. TGA shows that the skeletons of I and II are stable up to 372°C and 553°C, respectively. I exhibits fluorescence. © 2014 Institute of Chemistry, Slovak Academy of Sciences.
