Date of Publication
The first metal complex of di-2-pyridylmethanone p-nitrophenylhydrazone (dpknph), i.e. the title compound, fac-[ReCl(C17H13N5O2)(CO)3]·C2H6OS, crystallizes as well separated pseudo-tetrahedral DMSO (DMSO is dimethyl sulfoxide) and pseudo-octahedral fac-[ReCl(dpknph)(CO)3] moieties. Two N atoms from dpknph, three C atoms from the carbonyl groups and one chloride ion occupy the coordination sphere around rhenium. The coordinated dpknph ligand forms a six-membered ring in a boat conformation, with the pyridine rings in a butterfly formation. The p-nitrophenylhydrazone moiety is planar, with all C and N atoms in sp2-hybridized forms. The molecules pack as stacks of interlocked fac-[ReCl(dpknph)(CO)3]·DMSO units via a network of non-covalent bonds that include solute-solute, solvent-solute and - interactions.....
