“…Completeness of the Fe1 environment is achieved by three orthophosphate tetrahedra connected to the metal atom only by one vertex and one orthophosphate tetrahedron connected via an edge (the Fe1-O distances lie in the range 1.955 (3) to 2.060 (3) Å). In comparison with KCuFe(PO 4 ) 2 (Badri et al, 2011), the bond lengths of Fe2-O are very close in both structures. In KCuFe(PO 4 ) 2 this position is occupied by Fe 3+ , whereas in the structure of KMg 0.09 Fe 1.91 (PO 4 ) 2 it is occupied by both Mg and Fe.…”

KMg0.09Fe1.91(PO4)2, potassium [iron(II)/magnesium] iron(III) bis(orthophosphate), is a solid solution derived from compounds with general formula KM IIFe(PO4)2 (M II = Fe, Cu), in which the Mg atoms substitute Fe atoms only in the octahedrally surrounded sites. The framework of the structure is built up from [FeO5] trigonal bipyramids and [MO6] (M = (Fe, Mg) octahedra sharing corners and edges and connected by two types of bridging PO4 tetrahedra. The K+ cations are nine-coordinated and are situated in channels running along [101].

“…It should be emphasized that some members of this family have a number of significant physical properties. Thus, KCuFe[PO 4 ] 2 is an antiferromagnet, also demonstrating the electrochemical properties of conductivity based on the migration of potassium ions through open channels of the crystal structure (Badri et al, 2011).…”

Two novel phases, potassium copper aluminium bis(phosphate), KCuAl [PO 4 ] 2 (I), and potassium zinc aluminium bis(phosphate-silicate), K(Al,Zn) 2 [(P,Si)O 4 ] 2 (II), were obtained in one hydrothermal synthesis experiment at 553 K. Their crystal structures have been studied using single-crystal X-ray diffraction. (I) is a new member of the A + M 2+ M 3+ [PO 4 ] 2 family. Its open 3D framework built by AlO 5 and PO 4 polyhedra includes small channels populated by columns of CuO 6 octahedra sharing edges, and large channels where K + ions are deposited. It is assumed that the stability of this structure type is due to the pair substitution of Cu/Al with Ni/Fe, Co/Fe or Mg/Fe in different representatives of the series. From the KCuAl[PO 4 ] 2 structural features, one may suppose it is a potentially electrochemically active material and/or possible low-temperature antiferromagnet. In accordance with results obtained from X-ray diffraction data, using scanning electron microscopy, microprobe analysis and detailed crystal chemical observation, (II) is considered as a product of epitaxial intergrowth of phosphate KAlZn[PO 4 ] 2 and silicate KAlSi[SiO 4 ] 2 components having closely similar crystal structures. The assembly of 'coherent intergrowth' is described in the framework of a single diffraction pattern.

“…The magnetic measurements of the KCuFe-(PO 4 ) 2 representative of the described structure type has revealed the compound to be antiferromagnetic. The investigation of electrical and conductivity properties showed an activation energy of 1.22 eV and the K + ions as the charge carriers (Badri et al, 2011).…”

A novel phosphate, sodium zinc aluminium bis(phosphate), NaZnAl(PO 4 ) 2 , was obtained under mild-temperature hydrothermal conditions at 553 K. The crystal structure has been studied using single-crystal X-ray experimental data. The pseudo-hexagonal phase NaZnAl(PO 4 ) 2 crystallizes in the monoclinic space group P2 1 /c. Its unique crystal structure is based on a three-dimensional (3D) framework built by Zn-, Al-and P-centred tetrahedra sharing vertices. Channels parallel to the [101] and [101] directions are limited by six-and eight-membered windows, and incorporate Na atoms. The new compound is discussed as a member of the morphotropic series AMM 0 PO 4 , where A = Na, K, Rb or NH 4 , M = Cu, Ni, Co, Fe, Zn or Mg and M 0 = Fe, Al or Ga. The title compound is the first Na representative within the series and is characterized by a 3D architecture of tetrahedra populated in an ordered manner by Zn 2+ , Al 3+ and P 5+ ions. research papers Acta Cryst.
