摘要: Abstract Three heteronuclear Cu(II)/Na(I) complexes, [Cu2(salen)2Na(ClO4)(CH3CN)] (1) [Cu2(vanen)2Na2(μ1,1-NCS)2] (2) and [(Cu)2(L)2(Na)2(μ1,1-CH3CN)(H2O)(ClO4)]ClO4 (3), where H2salen = N,N′-ethylenebis-(salicylideneimine) H2vanen = N,N′-(1,2-ethylene)-bis(3-methoxysalicylideneimine), have been prepared characterized by elemental analyses, IR UV–Vis spectroscopy single crystal X-ray diffraction studies. Two Cu(II)–salen units are connected an Na ion in complex 1. Cu(II)–vanen–Na(I) moieties bridging thiocyanate groups 2. A novel end-on asymmetric acetonitrile is observed 3.
