Synthesis and characterisation of a new high pressure polymorph of Cu2WS4
Abstract
In this communication we report the synthesis and structural characterisation of a new body centred polymorph of Cu2WS4 prepared using hydrothermal methods. I–Cu2WS4 crystallises in space group I2m with cell parameters a = b = 5.44427(8), c = 10.0687(2) Å and has a new structure type containing layers of edge-sharing CuS4 and WS4 tetrahedra.
