Abstract
BeF2YbF2 crystallizes in the triclinic P1 space group. The structure is two-dimensional and consists of one BeF2 ribbon oriented in the (1, 0, 0) direction and one YbF2 sheet oriented in the (0, 0, 1) direction. In the BeF2 ribbon, there are four inequivalent Be2+ sites. In the first Be2+ site, Be2+ is bonded in a tetrahedral geometry to four F1- atoms. There are a spread of Be–F bond distances ranging from 1.43–1.69 Å. In the second Be2+ site, Be2+ is bonded in a tetrahedral geometry to four F1- atoms. There are a spread of Be–F bond distances ranging from 1.43–1.69 Å. In the third Be2+ site, Be2+ is bonded in a trigonal non-coplanar geometry to three F1- atoms. There is one shorter (1.49 Å) and two longer (1.52 Å) Be–F bond length. In the fourth Be2+ site, Be2+ is bonded in a trigonal planar geometry to three F1- atoms. There is one shorter (1.49 Å) and two longer (1.52 Å) Be–F bond length. There are eight inequivalent F1- sites. In the first F1- site, F1- is bonded in a distorted bent 120 degrees geometry to two Be2+ atoms. In the second F1- site, F1- is bonded in a bentmore »
