Crystal structures of the isotypic complexes bis(morpholine)gold(I) chloride and bis(morpholine)gold(I) bromide

The compounds bis(morpholine- κ N)gold(I) chloride, [Au(C4H9NO)2]Cl, 1, and bis(morpholine- κ N)gold(I) bromide, [Au(C4H9NO)2]Br, 2, crystallize isotypically in space group C2/c with Z = 4. The gold atoms, which are axially positioned at the morpholine rings, lie on inversion centres (so that the N — Au — N coordination is exactly linear) and the halide anions on twofold axes. The residues are connected by a classical hydrogen bond N — H...halide and by a short gold...halide contact to form a layer structure parallel to the bc plane. The morpholine oxygen atom is not involved in classical hydrogen bonding.
