多元金属硒化物以其丰富的结构化学和特殊的物理化学性能而成为固体化学研究的一个活跃领域。
本课题采用反应性熔盐法合成十个新的多元金属硒化合物,其中七个三元化合物KSnSe5,K7SnSe5,K4InSe3,K3InSe3,K2InSe2,AgBiS3,K4Sn3Se8,和三个四元化合物KAgBiSe4,K4Cu4GeSe13,K2AgIn3Se6。
采用单晶X-射线衍射法测定K2AgIn3Se6和K4Sn3Se8的晶体结构。K2AgIn3Se6 属于单斜晶系,空间群为C2/c ,晶胞参数:a = 11.6411(7) ?, b = 11.6348(8) ?, c = 21.4179(12) ?, V = 2874.0(9) ?3, Z = 8。K2AgIn3Se6 的晶体结构是由平行于(001)晶面的中性[K2AgIn3Se6]层沿c方向通过分子间力堆积而成的。K4Sn3Se8晶体属于正交晶系,空间群为Ccca ,晶胞参数:a = 8.2115(6) ?,b = 27.790(2) ?,c = 8.1865(6) ?,V = 1868.2(2) ?3 ,Z = 4。K4S...

Multinary metal selenides have extensively been studied because of their rich structural chemistry and chemical or physical properties.
In this dissertation, we synthesized ten novel multi-component metal selenides by reactive flux method at intermediate temperature, which are KSnSe5, K7SnSe5, K4InSe3, K3InSe3, K2InSe2, AgBiS3, K4Sn3Se8, KAgBiSe4, K4Cu4GeSe13, and K2AgIn3Se6.
The structures of K2AgIn3Se6 and K4Sn3Se8 have been determined by single-crystal X-ray diffraction. K2AgIn3Se6 cr...
