Synthesis and crystal structure of tricarbonylchlorido{1-[(pyridin-2-ylmethylidene)amino]adamantane}rhenium(I)

Abstract

The title compound, [ReCl(pyAm)(CO)3], where pyAm is 1-[(pyridin-2-ylmethylidene)amino]adamantane (C16H20N2), was synthesized from the reaction of [ReCl(CO)5] and pyAm in an equimolar ratio. The ReI atom resides in an octahedral C3ClN2 coordination sphere. The Re - C bond trans to the chloride ligand is noticeably longer compared to the other two Re - C distances. Weak C - H⋯Cl hydrogen-bonding interactions consoldiate the packing of the molecules. In this design, the pyAm ligand was employed due to its well-known pharmacokinetic properties.
