Materials Data on Eu2C(NO)2 by Materials Project
Eu2C(NO)2 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Eu3+ is bonded in a 7-coordinate geometry to three equivalent N3- and four equivalent O2- atoms. All Eu–N bond lengths are 2.66 Å. There are three shorter (2.32 Å) and one longer (2.36 Å) Eu–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 Eu3+ and one C4+ atom. O2- is bonded to four equivalent Eu3+ atoms to form a mixture of corner and edge-sharing OEu4 tetrahedra.
