Materials Data on Pr2C(NO)2 by Materials Project
Pr2C(NO)2 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Pr3+ is bonded in a 7-coordinate geometry to three equivalent N3- and four equivalent O2- atoms. All Pr–N bond lengths are 2.71 Å. There are three shorter (2.38 Å) and one longer (2.40 Å) Pr–O bond lengths. C4+ is bonded in a linear geometry to two equivalent N3- atoms. Both C–N bond lengths are 1.24 Å. N3- is bonded in a 1-coordinate geometry to three equivalent Pr3+ and one C4+ atom. O2- is bonded to four equivalent Pr3+ atoms to form a mixture of corner and edge-sharing OPr4 tetrahedra.
