crystallographic analysis shows that the molecule crystallizes in the monoclinic system, space group C2/c. In the complex, chloride was not coordinated as confirmed by conductivity measurements. The metal is coordinated to the oxime, imine, and amine nitrogen atoms and decomposes with loss of the organic ligand and halogen to leave metal oxide. The metal to ligand ratio was 1 : 2 by elemental analysis and mass spectrum
2-呋喃-2-基-1,2,3,4-四氢喹唑啉-2-甲醛肟 (HL) 和含有肟、亚胺和胺供体的三齿配体配合物与钴 (II) 盐反应得到通过光谱方法(FT-IR、NMR、UV-Vis、质量)、元素分析、磁化率、摩尔电导率和热分析(TG、DTA)技术合成和表征。从单晶X射线衍射阐明了HL的分子结构。X 射线晶体学分析表明该分子在单斜晶系、空间群 C2/c 中结晶。在复合物中,如电导率测量所证实的那样,氯化物没有配位。金属与肟、亚胺和胺氮原子配位并分解,失去有机配体和卤素,留下金属氧化物。金属与配体之比为 1:
