A novel layered oxysulfide intergrowth compound Sr4Mn2Cu5O4S5 containing a fragment of the α-Cu2S antifluorite structure
Abstract
Sr4Mn2Cu5O4S5 contains manganese oxide sheets separated by unusual antifluorite-type Cu3S3 layers in which copper(I) ions are distributed over three- and four-coordinate sites in a similar fashion to in α-Cu2−xS and suggestive of high two-dimensional copper ion mobility.
