N2 - Electron microprobe analyses of a suite of four sinhalites (all of gem quality) indicate that sinhalites (ideal formula MgAlBO) accommodate excess aluminium and small amounts of iron at the expense of magnesium. The results of structure determination and refinement, based upon single-crystal X-ray diffraction data, are in agreement with previous work. Sinhalite is isostructural with forsterite, having space group Pbnm. The cell parameters are a = 4.3320(4) Å, b = 9.8819(5) Å, c = 5.6813(4) Å. The structure was refined to R = 0.017, R = 0.019 with 427 observed reflections and 41 refinable parameters. The assumed ordering scheme was deduced from the microprobe analyses. -from Authors
