Penkvilksite-2O: Na₂TiSi₄O₁₁·2H₂O

A previous model of the crystal structure of penkvilksite-2O obtained by the order–disorder (OD) theory is confirmed by an independent structure determination using single-crystal X-ray diffraction data.

Cd₂Cu(PO₄)₂

Cd₂Cu(PO₄)₂ is the sixth known member of a series of inorganic compounds having a Cu₃(PO₄)₂-type structure and the general formula M1₂M2(XO₄)₂ (M1/M2 = Cd²⁺, Cu²⁺, Mg²⁺ and Zn²⁺; X = As⁵⁺, P⁵⁺ or V⁵⁺). The structure of Cd₂Cu(PO₄)₂ is built up of two types of mutually inter­connected chains, viz. [Cu(PO₄)₂]_n chains and [Cd₂O₁₀]_n double chains, both extending along the a axis.
