New metal-organic frameworks (MOFs) [Ni(C12N2H 10)-(H2O)][C6H3(COO) 2(COOH)] (I), [Co2(H2O)6][C 6H3(COO)3]2· (C 4N2H12)(H2O)2 (II), [Ni2(H2O)6][C6H3(COO) 3]2·(C4N2H 12)-(H2O)2 (III), [Ni(C13N 2H14)(H2O)][C6H3(COO) 2(COOH)] (IV), [Ni3(H2O)8][C 6H3(COO)3] (V) and [Co(C4N 2H4)(H2O)][C6H3-(COO) 3] (VI) {C6H3(COOH)3 = trimesic acid, C12N2H10 = 1,10-phenanthroline, C 4N2H12 = piperazine dication, C 13N2H14 = 1,3-bis(4-pyridyl)propane and C 4N2H4 = pyrazine} have been synthesized by using an interface between two immiscible solvents, water and cyclohexanol. The compounds are constructed from the connectivity between the octahedral M 2+ (M = Ni, Co) ions coordinated by oxygen atoms of carboxylate groups and water molecules and/or by nitrogen atoms of the ligand amines and the carboxylate units to form a variety of structures of different dimensionality. Strong hydrogen bonds of the type O-H...O are present in all the compounds, which give rise to supramolecularly organized higher-dimensional structures. In some cases π...π interactions are also observed. Magnetic studies indicate weak ferromagnetic interactions in I, IV and V and weak antiferromagnetic interactions in the other compounds (II, III and VI). All the compounds have been characterized by a variety of techniques. Wiley-VCH Verlag GmbH & Co. KGaA, 2008.
