The use of adjectival prefixes for anions is to be preferred instead of modified Levinson suffixes; accordingly, six minerals should be renamed as follows: apatite-(CaF) to fluorapatite, apatite-(CaOH) to hydroxylapatite, apatite-(CaCl) to chlorapatite, ellestadite-(F) to fluorellestadite, ellestadite-(OH) to hydroxylellestadite, phosphohedyphane-(F) to fluorphospho-hedyphane.
Chlorapatite (ClAp), [Ca.sub.10][([PO.sub.4]).sub.6][(Cl).sub.2], has been described in the hexagonal space group P[6.sub.3]/m, with cell parameters, a = b = 9.598(2) [Angstrom], c = 6.776(4) [Angstrom], Z = 1 (5).
