Abstract

A ternary metal selenide KInSe 2 has been synthesized by use of the reactive molten salt method. The reactants with molar ratio of n (K 2Se 3) : n (In) : n (Se) = 1 : 1 : 5 were reacted at 500°C for 5 days. The crystal structure of KInSe 2 was determined by X - ray structure analysis. KInSe 2 belongs to monoclinic system with space group C2/c. The unit cell parameters are a = 1.1414(2)nm, b = 1.1410(2)nm, c = 1.5586(3)nm, V = 1.9952(6)nm 3, Z = 16. KInSe 2 is a layered crystal containing 2D network of 2 [InSe 2] - anions and K + cations. The layers are packed in the sequence ABAB in the crystal. There are two crystallographically independent In atoms, both of which are coordinated to four μ 2 Se atoms to form slight distorted tetrahedra. Of the five crystallographically independent Se atoms, Se(3) and Se(5) are located on 2 - fold axes(4e). The K + ions are six - coordinated to Se.
