| Abstract: Two coordination compounds, {[M(L)2(H2O)2](ClO4)2·4H2O}n (M=Cu 1, Co 2; L=1,4-diazoniabicyclo[2.2.2]octane-1,4-diacetate), were synthesized and characterized by elemental analysis, IR, TGA and magnetic susceptibilities. Single-crystal structures show the two compounds both crystallize in monoclinic system, space group P21/c. Cu(Ⅱ) and Co(Ⅱ) ions are coordintated with six oxygen atoms from two water molecules and four ligands to form an octahedral geometry. Each ligand links two metal ions in a μ2-bridge coordination mode and two-dimensional wavelike structures are formed. Magnetic studies showed that weak antiferromagnetic interactions existed between the Cu(Ⅱ) ions in 1, and Co(Ⅱ) ions were located in a moderate ligand field in 2. CCDC: 684712, 1; 684713, 2. |
