The solvothermal synthesis and characterisation of [C 6 H 16 N 2 ][GaS 2 ] 2 ( 1 ), [C 6 H 16 N 2 ][Ga 2 Se 3 (Se 2 )] ( 2 ), and mixed‐metal phases with composition [C 6 H 16 N 2 ][Ga 2– x In x Se 3 (Se 2 )] (0 < x < 2)( 3 – 5 ), is described. These materials have been characterised by single‐crystal and powder X‐ray diffraction, thermogravimetric analysis and UV/Vis diffuse reflectance spectroscopy. The materials contain one‐dimensional anionic chains. In 1 , these chains consist of edge‐linked GaS 4 tetrahedra, whilst in 2 – 5 , the chains contain perselenide (Se 2 ) 2– units and comprise alternating four‐membered [M 2 Se 2 ] and five‐membered [M 2 Se 3 ] rings (where M = Ga, In). Compounds 3 – 5 represent the first examples of ternary mixed‐metal [M 2 Se 3 (Se 2 )] 2– chains.
