摘要
合成了二个内、外消旋的双(苯基亚砜)乙烷(α、β-Bphse)Cu(Ⅱ)配合物:[Cu2(α-Bphse)2(NO3)2](NO3)2(1)和[Cu2(β-Bphse)2(NO3)2](NO3)2(2).对其进行了元素分析、红外光谱及摩尔电导的测定,结果表明配体Bphse均以二个氧原子与Cu(Ⅱ)配位.在ESR谱图中,这二个配合物呈现△Ms=2的半场跃迁,且它们在室温下的μeff均较明显地小于Cu(Ⅱ)仅自旋的μeff,指明它们均为反铁磁性的双核配合物.
Two copper(Ⅱ) comlexes were synthesized, namely [Cu2 (α-Bphse)2 (NO3)2] (NO3)2 (1)and [Cu2 (β-Bphse)2 (NO3)2](NO3)2 (2) (α-and β-Bphse represented meso- and rac-form C6H5-S (O)-(CH2)2-S (O)-C6H5 respectively). They have been characterized by element analysis, IR and molar conductance. The results indicate that Bphse is coordinated to copper (Ⅱ) via two oxygenatoms and these complexes are binuclear. Moreover, X-band powder ESR spectra of these complexes at room temperture studied show the Ms=2 half field transition and the magnetic moments at room temperature (1. 23 and 1. 22 B. M respectively)are less than the Cu(Ⅱ) spin only value (1. 23 and 1. 22 B. M respectively)are less than the Cu(Ⅱ) spin only value (1. 73 B. M. ) that proves they have antiferromagnetic intramolecular interaction. So complexes (1) and (2) all are binuclear antiferromagnetic complexes.
