Dinickel(II) silicon bis[diphosphate(4−)], Ni2Si(P2O7)2, is isotypic with other phosphates of the formula M2Si(P2O7)2 (M = Co, Cd). All atoms except Si (site symmetry 2) are found in general positions. Ni2O10 dimers formed from edge-sharing NiO6 octahedra are linked by corners and O—P—O bridges, forming slabs parallel to (100), which are in turn interconnected by O—Si—O contacts.
