Hydrothermal synthesis and structural characterization of two unprecedented coordination polymers:: {Co3[O2C(CH2)4CO2]3[1,10′-phen]2}n and {Co2[O2C(CH2)3CO2]2[1,10′-phen]2}n

Two new cobalt (11) containing coordination polymers {Co-3[O2C(CH2)(4)CO2](3)[1,10'-phen](2)}(n) (1) and (Co-2[O2C(CH2)(3)Co-2](2)[1,10'-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, a = 9.0014(18) angstrom, b = 9.0573(18) angstrom, c = 13.327(3) angstrom, alpha = 97.93(3), beta = 100.06(3), gamma = 104.85(3), Z=1. Crystal data for compound 2: C34H32CO2N4O8, monoclinic P2(1)/c, a = 10.537(2) angstrom, b = 20.780(4) angstrom, c = 13.471(3) angstrom, beta = 100.63(3), Z=4. 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. (c) 2005 Elsevier B.V. All rights reserved.
