“…However, the species and name for an OH-dominant pertsevite had not been submitted to Commission on New Minerals, Nomenclature and Classification, International Mineralogical Association (CNMNC IMA) for approval. Additional investigations of OH-dominant pertsevite using secondary ion mass spectrometry (SIMS), including direct determination of hydrogen, gave an empirical ratio OH/F > 1, confirming previous data based on chemical compositions obtained by electron probe microanalysis (EPMA) (Galuskina et al 2008) and establishing the existence of OH-dominant pertsevite. The species and name pertsevite-(OH) were approved by the CNMNC in February 2009 (IMA 2008-060).…”

“…PowderCell for Windows version 2.4 (Kraus and Nolze 1996), based on the Rietveld method, was used to calculate the lattice parameters of pertsevite-(OH), d hkl calc and I calc . The starting lattice parameters and the atomic coordinates were taken from Galuskina et al (2008). The atomic coordinates were not released in the Rietveld refinement because release of the atomic coordinates did not improve the fit.…”

Pertsevite-(OH), end-member formula Mg 2 (BO 3 )(OH), is a new mineral found in a ludwigite-kotoite magnesian skarn from the Snezhnoye deposit in Sakha-Yakutia Republic, Russia. The Commission on New Minerals, Nomenclature and Classification, IMA (IMA 2008-060) has approved the mineral and the mineral name. Moreover, the Chairman of the CNMNC agreed to renaming pertsevite to pertsevite-(F). The two minerals constitute the pertsevite series with the general formula Mg 2 (It is associated with kotoite, szaibelyite, ludwigite-azoproite, clinohumite, hydroxylclinohumite, forsterite, chondrodite, calcite, REE-bearing sakhaite, sphalerite, and goethite. Ion microprobe analyses of pertsevite-(OH) using secondary ion mass spectrometry gave B, F, and H contents consistent with B and F contents determined by electron microprobe analyses (EMPA), and with OH contents calculated from EMPA data, confirming that OH/F ratio > 1 in pertsevite-(OH). Pertsevite-(OH) is orthorhombic, with space group Pnma. Cell dimensions refined from X-ray powder diffraction data are as follows: a = 20.499 (1), b = 11.900(1), c = 4.589(1) Å, and V = 1119.4(3) Å 3 . The strongest lines of the X-ray diffraction pattern are [(hkl), d-spacing in Å, (I)]: (331) 2.. The main bands in the FTIR spectrum of pertsevite-(OH) are 1354, 1261, 1178, 1022, 975, 929, 888, 745, 555 and OH-specific 3696, 3562, 3530 cm -1 .

“…This serves as an additional argument in favor of that the (BO 3 ) 3-↔ 3F -substitution is related just with the anionic [(BO 3 )F] 4-group and proceeds with the formation of the [F 4 ] tetrahedron(Fig. 3).A natural analogue of the α-Mg 2 (BO 3 ) 1+x F 1-3x compound (mineral pertsevite), the studied samples of which correspond to the formula Mg 2 (BO 3 ) 1-x [SiO 4 ] x (F,OH) 1-x (x ≤ 0.25)[16,28], also demonstrate the ability to complex anionicisomorphism. The isomorphic ((BO 3 ) 3-+ F -) ↔ [SiO 4 ] 4-substitution is manifested in pertsevite.…”

In the work the structures of fluoride borates demonstrating the substitution with the stoichiometry (BO 3 ) 3-↔ 3F -are analyzed and the specific role of tetrahedral anionic [X 4 ] 4-groups is revealed in this substitution. The possibility of the F-F interaction in [F 4 ] 4-groups uncharacteristic of ionic crystals is confirmed by ab initio quantum chemical simulation of the crystal structure of Ba 4-x Sr 3+x (BO 3 ) 4-y F 2+3y .
