Specific features of cation distribution in the crystal structure of mariinskite BeCr2O4 (Derivative of olivine-type structure)

Two samples of mineral mariinskite have been investigated by single-crystal X-ray diffraction, and their formulas were established to be Cr 1.43 Al 0.64 Be 0.9 O 4 (sample 1) and Cr 1.32 Al 0.74 Be 0.9 O 4 (sample 2). The parameters of their orthorhombic cells are, respectively, a = 4.487(1) Å, b =...
