Abstract

(Kr2F3)2KrF2(SbF6)2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of eight Kr2F3 clusters, four KrF2 clusters, and eight SbF6 clusters. In each Kr2F3 cluster, there are two inequivalent Kr sites. In the first Kr site, Kr is bonded in a linear geometry to two F atoms. There is one shorter (1.86 Å) and one longer (2.09 Å) Kr–F bond length. In the second Kr site, Kr is bonded in a linear geometry to two F atoms. There is one shorter (1.85 Å) and one longer (2.10 Å) Kr–F bond length. There are three inequivalent F sites. In the first F site, F is bonded in a bent 120 degrees geometry to two Kr atoms. In the second F site, F is bonded in a single-bond geometry to one Kr atom. In the third F site, F is bonded in a single-bond geometry to one Kr atom. In each KrF2 cluster, Kr is bonded in a linear geometry to two equivalent F atoms. There is one shorter (1.93 Å) and one longer (1.94 Å) Kr–F bond length. F is bonded in a single-bond geometry to one Kr atom. In each SbF6 cluster, Sb is bonded in an octahedral geometry to six F atoms. There is two shorter (1.92 Å) and four longer (1.93 Å) Sb–F bond length. There are six inequivalent F sites. In the first F site, F is bonded in a single-bond geometry to one Sb atom. In the second F site, F is bonded in a single-bond geometry to one Sb atom. In the third F site, F is bonded in a single-bond geometry to one Sb atom. In the fourth F site, F is bonded in a single-bond geometry to one Sb atom. In the fifth F site, F is bonded in a single-bond geometry to one Sb atom. In the sixth F site, F is bonded in a single-bond geometry to one Sb atom.
