摘　　要：报道了〔（ＮＨ４）２（１８Ｃ６）２〕〔Ｃｒ（ＣＳＮ）５·Ｃ２Ｈ５ＯＨ〕配合物的合成及其在乙腈和ＤＭＦ中的光化学性质．配合物在ＮｉＳＯ４滤光液及２５８ｎｍ滤光片照射后均发生光分解反应，初始反应为一级反应，速度常数随光强而增加，随入射光波长增加而减小．量子产率仅与照射光波长有关，且随波长的减小而增大。Synthesis and photochemical properties of the complex (NH 4) 2(18C6) 2 Cr(SCN) 5·C 2H 5OH have been reported in this paper.A photochemical decomposition reaction occurred under the radiation.The reaction is a first_order process at the beginning and the tate constant increased with light intensity and deceased with absorbed light wavelength.The reaction mechanism has been suggested.
