A new orthorhombic carbodiimide was obtained at x = 0.1. It coexists with SrNCN-type solid solutions between x = 0.2 and 0.5. The crystal structure of Ba0.9Sr0.1 NCN was determined using single-crystal X-ray and powder neutron diffraction data, and was found to adopt an orthorhombic Pnnm crystal structure. In this structure, both Ba2+ and Sr2+ cations are situated in an octahedron of N atoms of NCN2- anionic groups, and the (Ba/Sr)N-6 octahedra form a distorted rutile-type structure with C atoms bridging the N atoms.Elsevier2021-04engjournal articleAMhttp://hdl.handle.net/2115/87597https://doi.org/10.1016/j.jssc.2021.1220000022-4596Journal of solid state chemistry296122000https://eprints.lib.hokudai.ac.jp/dspace/bitstream/2115/87597/1/JSSC2021_122000.pdfapplication/pdf851.21 KB2021-04
