Materials Data on Ta2CN3 by Materials Project
Ta2N3C crystallizes in the hexagonal P6/mmm space group. The structure is three-dimensional and consists of one methane molecule and one Ta2N3 framework. In the Ta2N3 framework, Ta+3.50+ is bonded to six equivalent N3- atoms to form a mixture of distorted edge, face, and corner-sharing TaN6 pentagonal pyramids. All Ta–N bond lengths are 2.11 Å. N3- is bonded in a square co-planar geometry to four equivalent Ta+3.50+ atoms.
