Cu(I)-Hydrido complexes supported by dibenzo[ b,f ]azepinyl P -alkene hybrid ligands and stabilized by electrostatic interactions in a Cu-H⋯KCl⋯BR 3 arrangement can be trapped with CO 2 at low temperature to afford Cu(I)-formates. The complexes are isolable with and without a pendant BEt 3 group and show strong Cu-O and weak B-O interactions.
