NaSiCPO7 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. Na1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Na–O bond distances ran
KMg14CO16 crystallizes in the orthorhombic Pmmm space group. The structure is three-dimensional. K1+ is bonded to six O2- atoms to form distorted KO6 octahedra that share corners with two equivalent K
