In the asymmetric unit, two O atoms are in general positions, whereas all others atoms are in special positions of the space group<jats:italic>Imma<\/jats:italic>: the Sr cation and one P atom occupy the Wyckoff position 4<jats:italic>e<\/jats:italic>(<jats:italic>mm2<\/jats:italic>), Fe is on 4<jats:italic>b<\/jats:italic>(<jats:italic>2\/m<\/jats:italic>), Ni and the other P atom are on 8<jats:italic>g<\/jats:italic>(<jats:italic>2<\/jats:italic>), one O atom is on 8<jats:italic>h<\/jats:italic>(<jats:italic>m<\/jats:italic>) and the other on 8<jats:italic>i<\/jats:italic>(<jats:italic>m<\/jats:italic>). The three-dimensional framework of the crystal structure is built up by [PO<jats:sub>4<\/jats:sub>] tetrahedra, [FeO<jats:sub>6<\/jats:sub>] octahedra and [Ni<jats:sub>2<\/jats:sub>O<jats:sub>10<\/jats:sub>] dimers of edge-sharing octahedra, linked through common corners or edges. This structure comprises two types of layers stacked alternately along the [100] direction. The first layer is formed by edge-sharing octahedra ([Ni<jats:sub>2<\/jats:sub>O<jats:sub>10<\/jats:sub>] dimer) linked to [PO<jats:sub>4<\/jats:sub>] tetrahedra<jats:italic>via<\/jats:italic>common edges while the second layer is built up from a strontium row followed by infinite chains of alternating [PO<jats:sub>4<\/jats:sub>] tetrahedra and FeO<jats:sub>6<\/jats:sub>octahedra sharing apices. The layers are held together through vertices of [PO<jats:sub>4<\/jats:sub>] tetrahedra and [FeO<jats:sub>6<\/jats:sub>] octahedra, leading to the appearance of two types of tunnels parallel to the<jats:italic>a<\/jats:italic>- and<jats:italic>b<\/jats:italic>-axis directions in which the Sr cations are located. Each Sr cation is surrounded by eight O atoms.<\/jats:p>","DOI":"10.1107\/s205698901501779x","type":"journal-article","created":{"date-parts":[[2015,9,25]],"date-time":"2015-09-25T11:11:54Z","timestamp":1443179514000},"page":"1255-1258","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":12,"title":["Crystal structure of strontium dinickel iron orthophosphate"],"prefix":"10.1107","volume":"71","author":[{"given":"Said","family":"Ouaatta","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abderrazzak","family":"Assani","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohamed","family":"Saadi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lahcen","family":"El Ammari","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"329","published-online":{"date-parts":[[2015,9,26]]},"reference":[{"key":"pj2022_bb1","doi-asserted-by":"crossref","first-page":"i40","DOI":"10.1107\/S1600536813016504","volume":"69","author":"Alhakmi","year":"2013","journal-title":"Acta Cryst.
