N2 - 4,4′,4″-[1,3,5-Benzenetriyltris(carbonylimino)]trisbenzoic acid (H 3L), a C 3-symmetric ligand, was found to self-assemble into an interesting core-rosette structure driven by intermolecular hydrogen-bonding interactions. Reactions of this ligand with Zn 2+, Co 2+ and Cd 2+ under solvothermal conditions resulted in the formation of four new coordination polymers with interesting structural motifs: [Zn 2(L)(OH)(H 2O)(DMF)]·DMF·H 2O (1), [Co 3(L) 2(DMF)(H 2O)] ·DMF·3CH 3OH (2), [Co 1.5(L)(H 2O)(DMF)]·DMF (3), and [Cd 1.5(L)(H 2O)(DMF)]·DMF (4). Single-crystal structural analysis revealed that complex 1 exhibits a rare example of twofold interpenetrating two-dimensional CdI 2-type structure with tetranuclear Zn 4(μ 3-OH) 2(COO) 6(H 2O)(DMF) serving as secondary building unit (SBU), whereas in 2, the μ 3-oxo-tricobalt basic carboxylate SBUs are connected by L 3- ligands, leading to a twofold interpenetrating three-dimensional (3,6)-net framework. The isomorphous complexes 3 and 4 each has a (4,4)-grid layered architecture in which the SBU is a linear Co 3/Cd 3 cluster. The four coordination polymers were all further characterized by IR, thermogravimetric and powder X-ray diffraction (PXRD).
