Description
Summary:The trinuclear cation of the title compound, [Ni(3)(C(2)H(5)N(5))(6)(H(2)O)(6)][SiF(6)](3)·20H(2)O, 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 octa-hedral 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 hexa-fluroridosilicate anion lies on a site of 3 symmetry and the other lies on a site of symmetry. The hexa-cation, dianions and uncoordinated water mol-ecules inter-act through hydrogen bonds to form a three-dimensional network. One uncoordinated water molecule is disordered, with site occupancy 0.3.
