CdZn₂KB₂O₆F, a new fluoride borate crystal

CdZn₂KB₂O₆F consists of (001) layers with corner-sharing ZnO₃F tetra­hedra and BO₃ triangles. The Cd atoms occupy six-coordinated inter­layer sites and the K atoms are located in inter­layer channels.

Le phosphate de cobalt et de lithium à valence mixte Li_4+xCo_2−x(P₂O₇)₂ (x = 0,03): étude structurale et analyse de distribution de charge

The cation disorder in the crystal structure of the mixed valent lithium/cobalt(II/III) phosphate Li_4.03Co_1.97(P₂O₇)₂ is elucidated both from the analysis of the structural data and by means of the charge-distribution method which validate the proposed structural model.

KBa₇Mg₂B₁₄O₂₈F₅, a new borate with an unusual hepta­borate group and double perovskite unit

KBa₇Mg₂B₁₄O₂₈F₅, with a nominal 7:1 composition of BaB₂O₄ to KMg₂F₅, is formed by isolated B₇O₁₄ groups and double perovskite units.
