Synthesis, characterization and magnetochemical studies of some copper(II) complexes derived from n-salicylidene-n-alkanoylhydrazins: X-ray crystal and molecular structure of bis [monochloro-(μ-n-salicylidenemyristoylhydrazine)ono(−1)] dicopper(II)

Three types of copper(II) complexes, [Cu(HL)Cl · H2O] · xH2O, [Cu(HL)Cl}2] and [Cu(L)}2], derived from N-Salicylidene-n-alkanoylhydrazines (H2L) have been synthesized and characterized by elemental analyses, infrared spectra and field desorption mass spectra as well as variable temperature magnetic susceptibility measurements. The X-ray molecular structure of bis[monochloro(μ-N-salicylidene myri
从N衍生的三种类型的铜(II)配合物[Cu(HL)Cl·H 2 O]· x H 2 O,[Cu(HL)Cl} 2 ]和[Cu(L)} 2 ] -水杨基-正烷酰基肼(H 2 L)已经合成并通过元素分析,红外光谱和场解吸质谱以及可变温度磁化率测量来表征。双[一氯(μ- N-水杨基肉豆蔻酰肼)ONO '的X射线分子结构(-1)]二铜(II)表明该络合物是一种中心对称的二聚体,其中每个铜(II)处于扭曲的方锥环境中,并且在赤道平面上与ONO单负三齿酰基hydr配体配位。第四配位点被另一单体单元的对称相关苯氧基氧占据。氯离子占据第五轴向配位点。在不同温度(5–298 K)下的磁化率测量结果表明,水合氯配合物[Cu(HL)Cl·H 2 O]· x H 2 O是单体的,未检测到自旋-自旋相互作用,而无水氯配合物[Cu(HL)Cl} 2 ]是二聚体,并表现出与-2 J的强反铁磁耦合值范围466–477
