| Summary: | In the title compound, fac-[Re(C19H13N3S)(CO)3(H2O)]PF6·CH3OH, the coordination environment of the ReI atom is octahedral with a C3N2O coordination set. In this molecule, the N,N′ bidentate ligand, (E)-4-(benzo[d]thiazol-2-yl)-N-(pyridin-2-ylmethylidene)aniline, and the monodentate aqua ligand occupy the three available coordination sites of the [Re(CO)3]+ core, generating a `2 + 1' mixed-ligand complex. In this complex, the Re—C bonds of the carbonyl ligands trans to the coordinating N,N′ atoms of the bidentate ligand are longer than the Re—C bond of the carbonyl group trans to the aqua ligand, in accordance with the intensity of their trans effects. The complex is positively charged with PF6− as the counter-ion. In the structure, the complexes form dimers through π–π intermolecular interactions. O—H...O and O—H...N hydrogen bonds lead to the formation of stacks parallel to the a axis, which further extend into layers parallel to (0\overline{1}1). Through O—H...F hydrogen bonds between the complexes and the PF6−counter-anions, a three-dimensional network is established.
