Crystal structure of -aqua-[()-4-(benzo[]thia-zol-2-yl)--(pyridin-2-yl-methyl-idene)aniline-κ ,']tricarbonylrhenium(I) hexa-fluorido-phosphate methanol monosolvate.

In the title compound, -[Re(CHNS)(CO)(HO)]PF·CHOH, the coordination environment of the Re atom is octa-hedral with a CNO coordination set. In this mol-ecule, the ,' bidentate ligand, ()-4-(benzo[]thia-zol-2-yl)--(pyridin-2-yl-methyl-idene)aniline, and the monodentate aqua ligand occupy the three available coordination sites of the [Re(CO)] core, generating a '2 + 1' mixed-ligand complex. In this complex, the Re-C bonds of the carbonyl ligands to the coordinating ,' atoms of the bidentate ligand are longer than the Re-C bond of the carbonyl group to the aqua ligand, in accordance with the intensity of their effects. The complex is positively charged with PF as the counter-ion. In the structure, the complexes form dimers through π-π inter-molecular inter-actions. O-H⋯O and O-H⋯N hydrogen bonds lead to the formation of stacks parallel to the axis, which further extend into layers parallel to (01). Through O-H⋯F hydrogen bonds between the complexes and the PF counter-anions, a three-dimensional network is established.
