The unsymmetrical (mixed-ligand) nickel 1,2-dithiolene complexes Ni(pddt)(dmio) and Ni(pddt)(dmit) (where pddt is 6,7-dihydro-5H-1,4-dithiepin-2,3-dithiolate, dmio is 1,3-dithiol-2-one- 4,5-dithiolate, and dmit is 1,3-dithiol-2-thione-4,5-dithiolate) were synthesized and characterized. The new complexes were found to be soluble in organic solvents, from which single crystals and/or thin deposits can be obtained. In the solid state, the compounds behave as single-component semiconductors with low room temperature conductivity values
非对称(混配配体)镍1,2-二硫代烯醇络合物Ni(pddt)(dmio)和Ni(pddt)(dmit)(其中pddt是6,7-二氢-5H-1,4-二硫代环戊-2,3-二硫酸酯,dmio是1,3-二硫酮-2-酮-4,5-二硫酸酯,dmit是1,3-二硫酮-2-硫酮-4,5-二硫酸酯)已合成并表征。发现这些新的络合物在有机溶剂中溶解,可以从中得到单晶和/或薄膜沉积物。在固态中,这些化合物表现为具有低室温电导率值的单组分半导体。
