Materials Data on Be2CoN2(O3F4)2 by Materials Project
(BeNF4)2CoO6 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of two cobalt;hexahydrate molecules and four BeNF4 clusters. In each BeNF4 cluster, Be is bonded in a distorted trigonal non-coplanar geometry to three F atoms. There is two shorter (1.41 Å) and one longer (1.80 Å) Be–F bond length. N is bonded in a water-like geometry to two F atoms. There is one shorter (1.33 Å) and one longer (1.49 Å) N–F bond length. There are four inequivalent F sites. In the first F site, F is bonded in a bent 120 degrees geometry to one Be and one N atom. In the second F site, F is bonded in a single-bond geometry to one N atom. In the third F site, F is bonded in a single-bond geometry to one Be atom. In the fourth F site, F is bonded in a single-bond geometry to one Be atom.
