The first pyridyl N,N′-coordinated di-2-pyridyl ketone oxime, fac-tricarbonylchloro(di-2-pyridyl ketone oxime)rhenium(I) dimethyl sulfoxide solvate

The structure of the first metal compound of pyridyl N,N′-coordinated di-2-pyridyl ketone oxime (dpk-o), fac-tricarbonylchloro(di-2-pyridyl-κN ketone oxime)rhenium(I) dimethyl sulfoxide solvate, [ReCl(C11H9N2O)(CO)3] ·C2H6OS, (I), is reported. The coordinated atoms (two N atoms from the pyridyl rings, three C atoms from the carbonyl groups and one Cl atom) are in a distorted octahedral arrangement, with the major distortion being due to the constraints associated with the binding of dpk-o. The packing of the molecules shows antiparallel tapes of (I), with a network of classical (O···H-O) and non-classical (O···H-C) hydrogen bonds between the dimethyl sulfoxide solvate molecule and the complexed metal moiety.
