Abstract

The syntheses and structures of [Ni(H2O)6]2+[MF6]2- (M = Ti,Zr,Hf) and Ni3(py)12F6·7H2O are reported. The former three compounds are isostructural, crystallizing in the trigonal space group R3 (No. 148) with Z = 3. The lattice parameters are a = 9.489(4), c = 9.764(7) A ̊, with V = 761(1) Å3 for Ti; a = 9.727(2), c = 10.051(3) Å, with V = 823.6(6) Å3 for Zr; and a = 9.724(3), c = 10.028(4)Å, with V = 821.2(8)Å3 for Hf. The structures consist of discrete [Ni(H2O)6]2+ and [MF6]2- octahedra joined by OH⋯F hydrogen bond Large single crystals were grown in an aqueous hydrofluoric acid solution. Ni3(py)12F6·7H2O crystallizes in the monoclinic space group I2/a (No. 15) with Z = 4. The lattice parameters are a = 16.117(4), b = 8.529(3), c = 46.220(7) A ̊, β = 92.46(2)°, and V = 6348(5) A ̊3. The structure consists of discrete Ni(py)4F2 octahedra linked through HOH⋯F and HOH⋯O hydrogen bonding interactions. Single c were grown from a (HF)x·pyridine/pyridine/water solution.
