Abstract
In the title compound, [ReBr(C13H10N4)(CO)(3)], the Re-I atom has a distorted octahedral coordination environment. Two N atoms of the 5-phenyl-3-(pyridin-2- yl)-1H-1,2,4-triazole ligand and two of the three carbonyl groups occupy the equatorial plane of the complex, with the third carbonyl ligand and the bromide ligand in the axial positions. The three carbonyl ligands are arranged in a fac configuration around the Re I atom. Mutual N-H center dot center dot center dot Br hydrogen bonds arrange molecules into centrosymmetric dimers. Additional stabilization within the crystal structure is provided by C-H center dot center dot center dot O and C-H center dot center dot center dot Br hydrogen bonds, as well as by slipped pi-pi stacking interactions [centroid-to-centroid distance = 3.785 (5) angstrom], defining a three-dimensional network.Keywords
