Hydrothermal synthesis and structural characterization of two unprecedented coordination polymers: {Co3[O2C(CH2)4CO2]3 [1,100-phen]2}n and {Co2[O2C(CH2)3CO2]2[1,100-phen]2}n

Two new cobalt (II) containing coordination polymers {Co3[O2C(CH2)4CO2]3[1,100-phen]2}n (1) and {Co2[O2C(CH2)3CO2]2[1,100- phen]2}n (2) have been synthesized under the hydrothermal condition and characterized by elemental analyses, IR, TG analyses and the single crystal X-ray diffractions. Crystal data for compound 1: C42H42Co3N4O12, triclinic P-1, aZ9.0014(18) A ° , bZ9.0573(18) A ° , cZ13.327(3) A° , aZ97.93(3), bZ100.06(3), gZ104.85(3), ZZ1. Crystal data for compound 2: C34H32Co2N4O8, monoclinic P2(1)/c, aZ10.537(2) A ° , bZ20.780(4) A ° , cZ13.471(3) A ° , bZ100.63(3), ZZ4. Compound 1 exhibits a novel two-dimensional layer framework, in which the trinuclear Co clusters are linked by adipate anions. Compound 2 represents a one-dimensional chain. Furthermore, the magnetic behavior of compound 2 is studied. q 2005 Elsevier B.V. All rights reserved.
