SYNTHESIS, CHARACTERIZATION AND STRUCTURE OF [Co（DBP）₂·3Py]₂·2CHCl₃

【摘要】 <正> The mixed ligand complex of cobalt with dibutylphosphate （HDBP） and pyridine has been synthesized. Elemental analysis yields the result that the formula of this compound is Co（DBP）₂·3Py·CHCl₃ （Py=pyridine）. The thermal analsyis, visible spectra and magnetic properties of it have been studied as well. Single crystal structural analysis shows that the crystal is triclinic with space group P and the unit cell parameters are as follows:a=14.490（10）, α=90.37（4）°,b=15.721（7）, β=96.04（5）°,c=20.109（12）, γ=105.63（4）°.The final R factor is 0.0773. Two Co atoms are connected by two bridging DBP groups to form a dinuclear molecule [Co（DBP）₂·3Py]₂ which has a C_s, symmetry. Each cell contains two dinuclear molecules and four chloroform molecules. The cobalt is coordinated in an octahedral arrangement by three oxygen atoms and three nitrogen atoms, of which one oxygen atom comes from a monodentate DBP group, two oxygen atoms from two bridging DBP groups, and the three nitrogen atoms from the three pyridi更多还原
