The Mixed‐Anion compound La2S2(CN2)

Abstract

The new binary metal carbodiimide La2S2(CN2) was synthesized via solid‐state metathesis reaction. The crystal structure was solved and refined on basis of single‐crystal X‐ray diffraction data with space group C2/m. The structure is represented by a layered structure, based on alternating layers of lanthanum, sulfide, and carbodiimide units. A close resemblance of the structure with that of La2O2C2 is discussed, as well as the less‐common coordination number seven of the lanthanum atom.
