La_4.27Mg_2.89Zn₃₀, a new structure type with strong positional disorder

La_4.27Mg_2.89Zn₃₀, an inter­metallic compound, is a new structure type which crystallizes in the hexa­gonal space group P6₃/mmc. The structure is an inter­growth of fragments of the CaCu₅ and Th₂Ni₁₇ types. Strong positional disorder is observed along the six- and threefold axes.

Structure and ³¹P NMR spectroscopy of a new phosphate, Na₈Ca_1.5Mg_12.5(PO₄)₁₂

The novel structure of Na₈Ca_1.5Mg_12.5(PO₄)₁₂ consists of MgO_x (x = 5 and 6) polyhedra and MO₇ (M = Mg or Na) octa­hedra linked directly through common corners or edges to form a rigid three-dimensional skeleton, reinforced by corner-sharing between identical Mg₁₂MO₄₈ units.

Copper(II) manganese(II) ortho­phosphate, Cu_0.5Mn_2.5(PO₄)₂

The copper–manganese phosphate solid solution Cu_0.5Mn_2.5(PO₄)₂ was prepared by a reaction between its constituent oxides at 1223 K under argon. The compound has a graftonite-type structure, viz. (Mn,Fe,Ca,Mg)₃(PO₄)₂, with Cu^II located in one of three distinct metal cation sites.

Disordered La₃Cu_4.88Se₇

The crystal structure of La₃Cu_4.88Se₇ contains edge-sharing [LaSe₆] and [LaSe₇] polyhedra, which are surrounded by copper ions. The five positions for copper determine an ionic diffusion pathway.
