New heterolepticcopper(I) dithiocarbamate and xanthatecomplexes of the general formula [(PPh3)2CuL] (L = N-(4-pyridyl)-N-furfuryldithiocarbamate L1 (1), thiomorpholinedithiocarbamate L2 (2), phenylpiperazinedithiocarbamate L3 (3), furfurylxanthate L4 (4) and pyridine-4-xanthate L5 (5) have been synthesized by metathesis reactions of the precursor complex [Cu(PPh3)2NO3] and potassium salts of the
通式[(PPh 3)2 CuL]的新杂合铜(I)二硫代氨基甲酸铜和黄药酸酯配合物(L = N-(4-吡啶基)-N-糠基二硫代氨基甲酸酯L1(1),硫吗啉代二硫代氨基甲酸酯L2(2),苯基哌嗪二硫代氨基甲酸酯L3(3),通过前体配合物[Cu(PPh 3)2 NO 3的复分解反应合成了糠基黄原酸酯L4(4)和吡啶-4-黄原酸酯L5(5)。]和配体(KL)的钾盐以等摩尔比计。这些配合物已通过元素分析和光谱法(IR,UV-Vis。,1 H,13 C和31 P NMR)进行了表征,其结构已通过X射线晶体学得以阐明。在所有五个结构中,发现铜原子都位于扭曲的四坐标(P 2 S 2)四面体几何形状内。的非线性光学性质1 - 5和的电子吸收带1和5已经分别通过DFT和TD-DFT方法进行了研究。在室温下,所有络合物在二氯甲烷溶液中均具有强发光性。的压制小球σ室温的〜10值-8 -10 -5 小号厘米-1显示他们的弱导电行为。
