چکیده
In the title salt, [Ni(C12H14N6O)2](CF3SO3)2·2H2O, the Ni(II) cation is located on an inversion centre and is coordinated by six N atoms from two tridentate 1-meth-oxy-2,2,2-tris-(pyrazol-1-yl)ethane ligands in a distorted octa-hedral geometry. The Ni-N distances range from 2.0594 (12) to 2.0664 (12) Å, intra-ligand N-Ni-N angles range from 84.59 (5) to 86.06 (5)°, and adjacent inter-ligand N-Ni-N angles range between 93.94 (5) and 95.41 (5)°. In the crystal, inversion-related pyrazole rings are π-π stacked, with an inter-planar spacing of 3.4494 (18) Å, forming chains that propagate parallel to the a-axis direction. Inter-molecular O-H⋯O hydrogen bonds are present between water mol-ecules and tri-fluoro-methane-sulfonate anions.

The title compound, C12H14N6O, consists of three pyrazole rings bound via nitro-gen to the distal ethane carbon of meth-oxy ethane. The dihedral angles between the three pyrazole rings are 67.62 (14), 73.74 (14), and 78.92 (12)°. In the crystal, mol-ecules are linked by bifurcated C-H,H⋯N hydrogen bonds, forming double-stranded chains along [001]. The chains are linked via C-H⋯O hydrogen bonds,...
