在去离子水中合成了标题配合物[Co(py)3(H2O)3](1,5-nds)(py=吡啶,1,5-nds=1,5-萘二磺酸根离子),通过红外光谱、X射线单晶衍射、热分析等手段对配合物进行了表征。结果表明,该配合物晶体属于单斜晶系,空间群为C2/c。晶体学参数:a=1.5912(3)nm,b=1.2206(2)nm,c=1.4855(3)nm,α=90°,β=98.18(3)°,γ=90°,V=2.8558(10)nm3,Z=4。每个钴离子与3个吡啶分子及3个水分子配位,1,5-萘二磺酸阴离子起到平衡电荷的作用。
The title complex [Co (py) 3 (H2O) 3] (py = pyridine, 1,5-nds = 1,5-naphthalenedisulfonate) was synthesized in deionized water by IR, X-ray single crystal diffraction, thermal analysis and other means of the complexes were characterized. The results show that the crystal belongs to the monoclinic system with space group C2 / c. Crystallographic parameters: a = 1.5912 (3) nm, b = 1.2206 (2) nm, c = 1.4855 (3) nm, α = 90 °, β = 98.18 (3) °, γ = 90 °, V = 2.8558 10) nm3, Z = 4. Each cobalt ion coordinates with three pyridine molecules and three water molecules, and the 1,5-naphthalene disulfonate anion plays a role of charge balance.
