Name:
after Rupert Hochleitner (1954- ), mineralogist specializing in systematic mineralogy, and famous for authorship of mineral-collecting / identification guidebooks. Also known as a long time editor-in-chief of the journal LAPIS ( https://www.strongnations.com/gs/show.php?gs=3&gsd=9045 )
Isostructural with benyacarite and pleysteinite. Seems to be the Ti analogue of benyacarite and TiO-analogue of pleysteinite.
Note: type locality set to the main-category locality due to some misfits between the IMA-NMNC Newsletter's data ("64 to 76 m level") and the Mindat sublocality ("67 m level").
Structure details:
* corner-sharing linear trimers comprising Ti-centred octahedra
* 10-member rings, || (010), arise from corner-sharing between the trimers and the phosphate groups;
* the phosphate tetrahedra also share cornerns, along [010], with MnO2(H2O)4 octahedra;
* K+ and water located within the rings.

Moderate
Pleochroism:
Non-pleochroic
Comments:
2V could not be measured because of the presence of apparent sector zoning, which distorts the conoscopic figure and makes extinction observations unreliable.
