2-3,5-diamino-4H-1,2,4-triazole)trinickel(II) tris(hexafluoridosilicate) icosahydrateAbstract: The trinuclear cation of the title compound, [Ni3(C2H5N5)6(H2O)6][SiF6]3·20H2O, has the six 3,5-diamino-1,2,4-triazole ligands each bridging two metal atoms; the metal atom in the middle, which lies on a special position (of 32 site symmetry), is connected to six N atoms in an octahedral geometry. The other metal atom, which lies on a special position (of 3 site symmetry), is connected to three N atoms and three O atoms. One hexafluroridosilicate anion lies on a site of 3 symmetry and the other lies on a site of 
symmetry. The hexacation, dianions and uncoordinated water molecules interact through hydrogen bonds to form a three-dimensional network. One uncoordinated water molecule is disordered, with site occupancy 0.3.
