fac-[N,N′-Bis(3-chloro-2-fluorobenzylidene)ethylenediamine]bromidotricarbonylrhenium(I)
In the title compound, [ReBr(C(16)H(12)Cl(2)F(2)N(2))(CO)(3)], the Re atom is in a slightly distorted octahedral coordination environment with the three carbonyl ligands having a fac configuration. The diimine ligand is equatorial and is bonded to the Re centre in an N,N′-bidentate chelating fashio...

Sumario: | In the title compound, [ReBr(C(16)H(12)Cl(2)F(2)N(2))(CO)(3)], the Re atom is in a slightly distorted octahedral coordination environment with the three carbonyl ligands having a fac configuration. The diimine ligand is equatorial and is bonded to the Re centre in an N,N′-bidentate chelating fashion, with a bite angle of 77.7 (2)°. The dihedral angle between the two benzene rings is 88.7 (6)°. In the crystal structure, there are F⋯O [2.856 (9) Å], Cl⋯C [3.150 (8) Å] and O⋯C [2.984 (10) Å] contacts which are shorter than the sum of the van der Waals radii for these atoms. In addition, symmetry-related molecules are linked via intermolecular C—H⋯O, C—H⋯Br and the F⋯O interactions into one-dimensional chains extending along the a axis. The crystal structure is further stabilized by intermolecular π–π interactions [centroid–centroid distance = 3.571 (5) Å]. |
