金刚烷胺水杨醛Schiff碱过渡金属(Ⅱ)配合物的合成与表征

Syntheses and characterization of transition metal(Ⅱ) complexes of Schiff base derived from adamantaneamine and salicylaldehyde

合成了金刚烷胺水杨醛Schiff碱配体(C17H21NO,以HL表示)与5种过渡金属(Ⅱ)的新的配合物[MCl2(HL)2](M=Mn(Ⅱ)、Co(Ⅱ)、Ni(Ⅱ)、Cu(Ⅱ)、Cd(Ⅱ)),用元素分析、摩尔电导、红外光谱、1H NMR谱和热重分析对产物进行了表征;讨论了配体与中心金属离子的键合情况,并推测了配合物的结构.根据表征结果和参考文献得出:每一配合物的中心金属离子与2个Schiff碱配体中的酚羟基氧及2个氯离子发生配位,配位数为4.

Five new solid complexes were synthesized by the coordination of tranisition metals（ Ⅱ ） with a Schiff base （C17H21NO, HL） derived from adamantaneamine and salicylaldehyde, and characterized by elemental analysis, molar conductance, infrared spectra, iH NMR spectra, thermal analysis. Their chemical formula were [MC12（HL）2]（M=Mn（Ⅱ）, Co（Ⅱ）, Ni（Ⅱ）, Cu（Ⅱ）, Cd（Ⅱ） ）. The coordination modes of the bonding in these complexes were discussed and their possible structure were proposed. It was concluded that every central M（ Ⅱ ） ion in the complexes coordinates with both two Schiff base ligands via two oxygen atoms of the phenol hydroxy group and two chloride anions. Their coordination numbers was verified to be 4.
