Kyawthuite
Kyawthuite is a rare mineral[1] with a simple formula: Bi3+Sb5+O4.[2] It is a natural bismuth antimonate. Kyawthuite is monoclinic, with space group I2/c, and is isostructural with clinocervantite,[1] its trivalent-antimony-analogue.[3] Kyawthuite is also an antimony-analogue of clinobisvanite.[4] Kyawthuite was discovered in the vicinity of Mogok township in Myanmar, an area famous of various gemstone minerals.[5]
