In the tenth F1- site, F1- is bonded in a 4-coordinate geometry to one Ca2+ and three equivalent Ho3+ atoms. In the eleventh F1- site, F1- is bonded in a distorted trigonal planar geometry to three Ho3+ atoms. In the twelfth F1- site, F1- is bonded in a trigonal non-coplanar geometry to three Ho3+ atoms. In the thirteenth F1- site, F1- is bonded in a distorted trigonal planar geometry to one Ca2+ and two equivalent Ho3+ atoms. In the fourteenth F1- site, F1- is bonded in a distorted single-bond geometry to four Ho3+ atoms. In the fifteenth F1- site, F1- is bonded in a trigonal non-coplanar geometry to three Ho3+ atoms. In the sixteenth F1- site, F1- is bonded in a distorted single-bond geometry to four Ho3+ atoms. In the seventeenth F1- site, F1- is bonded in a 1-coordinate geometry to three Ca2+ atoms. In the eighteenth F1- site, F1- is bonded in a trigonal non-coplanar geometry to two equivalent Ca2+ and one Ho3+ atom. In the nineteenth F1- site, F1- is bonded in a 3-coordinate geometry to three equivalent Ca2+ atoms. In the twentieth F1- site, F1- is bonded to four Ca2+ atoms to form distorted corner-sharing FCa4 trigonal pyramids.
