title: Synthesis and crystal structure of tri-carbonyl-chlorido-{1-[(pyridin-2-yl-methyl-idene)amino]-adamantane}rhenium(I).
abstract: The title compound, [ReCl(pyAm)(CO)3], where pyAm is 1-[(pyridin-2-yl-methyl-idene)amino]-adamantane (C16H20N2), was synthesized from the reaction of [ReCl(CO)5] and pyAm in an equimolar ratio. The ReIatom resides in an octa-hedral C3ClN2coordination sphere. The Re-C bondtransto the chloride ligand is noticeably longer compared to the other two Re-C distances. Weak C-H⋯Cl hydrogen-bonding inter-actions consoldiate the packing of the mol-ecules. In this design, the pyAm ligand was employed due to its well-known pharmacokinetic properties.
