..., Sr, Pb) cation occurs in a distorted 7+3-coordinated polyhedron located in the eight-membered ring. CaBe 2 P 2 O 8 and SrBe 2 P 2 O 8 are isostructural with the minerals hurlbutite and strontiohurlbutite, respectively. The structure of BaBe 2 P 2 O 8 consists of double layers of tetrahedra, which...
