In the title salt, [Ni(C12H14N6O)2](CF3SO3)2·2CH3OH, the NiII ion is coordinated by six N atoms from two tridentate 1-methoxy-2,2,2-tris(pyrazol-1-yl)ethane ligands in a distorted octahedral geometry. The NiII ion is situated on an inversion centre. The Ni-N distances range from 2.0589 (19) to 2.0757 (19) Å, intra-ligand N-Ni-N angles range from 84.50 (8) to 85.15 (8)°, and adjacent inter-ligand N-Ni-N angles range between 94.85 (8) and 95.50 (8)°. In the crystal, O-HO hydrogen bonds between methanol solvent molecules and trifluoromethanesulfonate anions are observed.
Pyrazole-based tridentate ligands are drawing attention because of their topology and the nature of the donor atoms, see: Paulo et al. (2004); Bigmore et al. (2005). For the synthesis of the ligand, see: Maria et al. (2007). The compound reported here was prepared as part of our ongoing research effort to study nitrogen donor tridentate scorpionate ligands coordinating to nickel, see: Lyubartseva et al. (2011, 2012); Lyubartseva & Parkin (2009).
