Single crystals of magnesium copper(II) bis[orthophosphate(V)] monohydrate, Mg1.65Cu1.35(PO4)2·H2O, were grown under hydrothermal conditions. The crystal structure is formed by three types of cationic sites and by two unique (PO4)3−anions. One site is occupied by Cu2+, the second site by Mg2+and the third site by a mixture of the two cations with an Mg2+:Cu2+occupancy ratio of 0.657 (3):0.343 (3). The structure is built up from more or less distorted [MgO6] and [(Mg/Cu)O5(H2O)] octahedra, [CuO5] square-pyramids and regular PO4tetrahedra, leading to a framework structure. Within this framework, two types of layers parallel to (-101) can be distinguished. The first layer is formed by [Cu2O8] dimers linked to PO4tetrahedraviacommon edges. The second, more corrugated layer results from the linkage between [(Cu/Mg)2O8(H2O)2] dimers and [MgO6] octahedra by common edges. The PO4units link the two types of layers, leaving space for channels parallel [101], into which the H atoms of the water molecules protrude. The latter are involved in O—H...O hydrogen-bonding interactions (one bifurcated) with framework O atoms across the channels.

Single crystals of strontium tetracobalt tris(orthophosphate) hydroxide, SrCo4(OH)(PO4)3, were grown serendipitously under hydrothermal conditions at 473 K. The crystal structure consists of undulating chains of edge-sharing [CoO6] octahedra that are linked into (010) layers by common vertices between chains. Adjacent layers are linked along [010] into a framework structure by tetrahedral [CoO4] units and by PO4 tetrahedra. The framework delimits channels extending along [100] in which the eleven-coordinate strontium cations are situated. Bifurcated O—H...O hydrogen bonds of weak strengths consolidate the crystal packing. The title compound was also characterized by infrared spectroscopy.
