Abstract

Krinovite, a meteoritic silicate mineral with ideal crystal chemical formula Na2Mg4Cr2[Si6018]02, is triclinic, space group Pbar1, with a = 10.238(4), b = 10.642( 4), c = 8.780(3) Å, alfa = 105.15(3)°, beta = 96.50(4)°, gamma = 125.15(3)°. The crystal structure of krinovite has been refined to R = 0.065, Rw= 0.067 for 1661 independent reflections. Krinovite is a member of the aenigmatite graup, and is characterized by octahedral walls connected through tetrahedral chains with appendices and additional insular octahedra.
