Structural analysis re-vealed that 1, 3, and 4 are one-dimensional chain-like coordi-nation polymers. In 1 distorted octahedral MnN3O3 and in 3square-pyramidal CuN3O2 coordination is satisfied by threenitrogen atoms and an appended carboxylate oxygen atom ofthe ligand, and an oxygen atom belonging to the carboxylategroup of an adjacent molecule. In 4 trigonal bipyramidalZnN3O2 coordination environment is provided by two nitro-gen atoms and an appended carboxylate oxygen atom of theligand in the equatorial plane, and the two axial positionsare satisfied by a tertiary amine nitrogen and an oxygen atombelonging to the carboxylate group of an adjacent molecule.In 1 the Mn" center is coordinated by an additional watermolecule. In these complexes each monomeric unit is se-quentially connected by syn-anti carboxylate bridges. Tem-perature-dependent magnetic susceptibilities for 1 and 3 aremeasured, revealing antiferromagnetic interactions throughsyn-anti carboxylate bridges between the M" centers. Analy-sis of the crystal packing diagram reveals that in 1 extensive7C-7E stacking involving alternate pyridine rings of adjacent1D chain exists, which eventually lead to the formation of a2D network structure. 收起
