The reaction of the potentially bidentate aroylhydrazone-based N,N-donor ligands N-(di(pyridin-2-yl)-methylene)benzohydrazide (Hdpmb) and 3-((pyridin-2-yl)methyleneamino)-2,3-dihydro-2-(pyridin-2-yl)quinazolin-4-(1H)one (Hppq) with [Re(CO)5Cl] in alcohol led to the isolation of the neutral complexes fac-[Re(CO)3Cl(Hdpmb)] (1) and fac-[Re(CO)3Cl(Hppq)] (2) respectively. Spectroscopic data and the X-ray crystal structures of the complexes are reported. The cell parameters of the complexes are 1: monoclinic, P21/c, a = 13.7393(9) Å, b = 12.0512(8) Å, c = 13.3543(9) Å, β = 107.105(2)°, V = 2113.4(2) Å3, R 1 = 0.0317, wR 2 = 0.0699; and 2.½ ethanol:monoclinic, P21/c, a = 17.607(1) Å, b = 20.826(1) Å, c = 13.5887(8) Å, β = 101.875(2)°, V = 4876.0(5) Å3, R 1 = 0.0228, wR 2 = 0.0503. The reaction of the potentially bidentate aroylhydrazone-based N,N-donor ligands 3-((pyridin-2-yl)methyleneamino)-2,3-dihydro-2-(pyridin-2-yl)quinazolin-4-(1H)one and N-(di(pyridin-2-yl)-methylene)benzohydrazide (NN) with [Re(CO)5Cl] in alcohol led to the isolation of the neutral complexes fac-[Re(CO)3Cl(NN)].
