About Hejtmanite
Formula:
Ba2Mn2+4Ti2(Si2O7)2O2(OH)2F2
Colour:
Brownish to golden yellow
Lustre:
Vitreous
Hardness:
4½
Specific Gravity:
3.97 - 4.06
Crystal System:
Triclinic
Member of:
Name:
Named in honour of Prof. RNDr. Bohuslav Hejtman (12 August 1911 StrannĂĄ u Kamenice nad Lipou - 18 September 2000 Praha), professor of petrology at Charles University in Prague, Czech Republic.
The Mn analogue of bafertisite (redefined as so basing on the Mbolve Hill material).
Previously reported to be monoclinic, which was proved wrong.
Chemistry is somewhat similar to that of perraultite. Compare UM1989-33-SiO:BaHMnTi.
Hejtmanite belongs to a group of titanosilicates built of TS (titanosilicate) and I (intermediate) blocks. In this group the TS block consists of HOH sheets, with H standing for heteropolyhedral sheets (penta- and hexacoordinated), and O for central octahedral (trioctahedral) sheet (Sokolova, 2010).
Hejtmanite is a Group-II TS-block mineral, which indicates that the (Ti+Nb) to (Si2O7) ratio is 2:2. In hejtmanite the O sheet consists of five hexacoordinated MO sites occupied mainly by Mn, surrounded by O or OH. The H sheet has (1) two hexacoordinated MH sites (mainly Ti, surrounded by O or F), and (2) four tetrahedral silicon sites. The I block comprises a layer of [12]Ba atoms, that reside within two AP(1,2) sites. Ba is surrounded by O or F. Four (XO) sites equal to two (XO M) and two (XO A) sites, corresponding to O2(OH)2 (Sokolova et al., 2016).
