Hydrothermal synthesis and structural characterization of two unprecedented coordination polymers: {Co 3[O 2C(CH 2) 4CO 2] 3[1,10′-phen] 2} n and {Co 2[O 2C(CH 2) 3CO 2] 2[1,10′-phen] 2} n

Abstract

Two new cobalt (II) containing coordination polymers {Co 3[O 2C(CH 2) 4CO 2] 3[1,10′-phen] 2} n ( 1) and {Co 2[O 2C(CH 2) 3CO 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: C 42H 42Co 3N 4O 12, triclinic P-1, a=9.0014(18) Å, b=9.0573(18) Å, c=13.327(3) Å, α=97.93(3), β=100.06(3), γ=104.85(3), Z=1. Crystal data for compound 2: C 34H 32Co 2N 4O 8, monoclinic P2(1)/ c, a=10.537(2) Å, b=20.780(4) Å, c=13.471(3) Å, β=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.
