The complex reacts with the potentially bidentate 8-hydroxyquinoline (Hquin) and N-phenylsalicylideneimine (Hpsal), and potentially terdentate ligands di-2-pyridyl ketone and 2,6-bis(hydroxymethyl)pyridine (H2L) to form the products , , > and cis-, respectively.The first three products are identical to those isolated earlier by the reactions of trans- with these ligands, while in the latter product the HL(1-) ligand acts as a bidentate N,O(1-)-donor, spanning one axial (O(1-) trans to Re=O) and one equatorial co-ordination site.These reactions present an alternative synthetic route to monooxorhenium(V) complexes.The complex cis- crystallizes in the orthorhombic space group P2₁2₁2₁ with cell parameters a = 10.019(3), b = 12.457(6), c = 19.53(1) Angstroem, U = 2436.5 Angstroem³, Z = 4, R = 0.059 and R' = 0.074 for 1330 reflections with F₀ > 4?(F₀).
