Synthesis and crystal structure of (1,8-naphth-yridine-κ ,')[2-(1-pyrazol-1-yl)phenyl-κ , ]iridium(III) hexa-fluorido-phosphate di-chloro-methane monosolvate.

The solvated title salt, [Ir(CHN)(CHN)]PF·CHCl, was obtained from the reaction between 1,8-naphthyridine (NAP) and an orthometalated iridium(III) precursor containing a 1-phenyl-pyrazole (ppz) ligand. The asymmetric unit comprises one [Ir(ppz)(NAP)] cation, one PF counter-ion and one CHCl solvent mol-ecule. The central Ir atom of the [Ir(ppz)(NAP)] cation is distorted-octa-hedrally coordinated by four N atoms and two C atoms, whereby two N atoms stem from the NAP ligand while the ppz ligands ligate through one N and one C atom each. In the crystal, the [Ir(ppz)(NAP)] cations and PF counter-ions are connected with each other through weak inter-molecular C-H⋯F hydrogen bonds. Together with an additional C-H⋯F inter-action involving the solvent mol-ecule, a three-dimensional network structure is formed.
