Abstract:

We have synthesized a new ternary nitride, Ca3VN3, from the binary nitrides at high temperature. The refined structure was solved in the P21 sub 1 m space group with lattice constants a6.717 2, b5.064 2, c6.720 3, Beta78.88 3, Z2, and R3.2, Rw3.7. The structure is related to the recently reported A3MN3 compounds 1 with sheets of VN36- trigonal planar units and calcium ions. Ca3VN3 is insulating with V3 in the low-spin state, S0.
