The crystal structure described by Ni(Pt3O4)4 crystallizes in the orthorhombic Pmmm space group. There are five inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a distorted square co-planar geometry to four equivalent O(1) atoms. In the second Pt site, Pt(2) is bonded in a square co-planar geometry to four equivalent O(2) atoms. In the third Pt site, Pt(3) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. In the fourth Pt site, Pt(4) is bonded in a distorted square co-planar geometry to four equivalent O(1) atoms. In the fifth Pt site, Pt(5) is bonded in a square co-planar geometry to four equivalent O(2) atoms. Ni(1) is bonded in a body-centered cubic geometry to eight equivalent O(1) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Pt(1), one Pt(3), one Pt(4), and one Ni(1) atom to form a mixture of edge and corner-sharing ONiPt3 trigonal pyramids. In the second O site, O(2) is bonded in a trigonal planar geometry to one Pt(2), one Pt(3), and one Pt(5) atom. is represented by the CIF file [CIF]
