Abstract

(Ni)4(Ce(NO2)12)2(N2)5 crystallizes in the cubic Pn-3 space group. The structure is zero-dimensional and consists of ten ammonia molecules, four nickel molecules, and two Ce(NO2)12 clusters. In each Ce(NO2)12 cluster, Ce3+ is bonded in a cuboctahedral geometry to twelve equivalent O2- atoms. All Ce–O bond lengths are 2.68 Å. N+2.18+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.22 Å) and one longer (1.26 Å) N–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Ce3+ and one N+2.18+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one N+2.18+ atom.
