Bis(μ‐acetato)(μ‐2,6‐bis­{[(2‐hydroxy­ethyl)(2‐pyridylmeth­yl)amino]meth­yl}‐4‐methyl­phenolato)dinickel(II) hexa­fluoro­phosphate hemihydrate

The asymmetric unit of the title compound, Ni₂(C₂₅H₃₁N₄O₃)(C₂H₃O₂)₂]PF₆·0.5H₂O, consists of two dinuclear nickel cations, two hexa­fluoro­phosphate anions and one water mol­ecule of crystallization. Within each cation, the Ni atoms are bridged by two exogenous acetate groups and an endogenous cresol O atom of a phenolate‐based `end‐off' compartmental ligand that possesses two pendant chelating arms attached to the ortho positions of the phenol ring. Each Ni atom is six‐coordinate with a slightly distorted octa­hedral geometry. The two symmetry‐independent cations are linked into a dimeric unit through O—H?O hydrogen bonds. Additional O—H?O, C—H?F and C—H?O inter­molecular inter­actions link all of the units in the structure into a three‐dimensional framework.
