EnglishThe reaction of [Mo(CO)6] with the macrocyclic ligand 6,7,16,17-tetrahydro-15H dibenzo[e,n][1,4,8,12]dioxa-diazacyclopentadecine (L1) in n-octane, gives [Mo(CO)4L1]. The crystal and molecular structure of [ Mo(CO)4L1] · 5 C6H5CH3 has been solved by X-ray diffraction methods. It is a monomer with Mo(0) co-ordinated to four carbon monoxide molecules and two iminonitrogens in a pseudo-octahedral geometry; crystals are monoclinic, space group P21/c, with a= 15.625(4), b= 11.554(3), c= 14.590(3)Å, β= 109.01(2)°, and Z= 4. Final R= 0.065 for 933 observed reflections. The reaction of [Mo(CO)3(C6H5CH3)] with L1 in methanol gives the orange-red crystalline complex [{Mo(CO)3L1}x] (2). By reacting the complex [Mo(CO)3(C6H5CH3)] with N,N-bis(3-aminopropyl)methylamine and 2,2′-(ethylenedioxy) dibenzaldehyde (1:1:1 ratio), in toluene, the complex [Mo(CO)3L2](5)(L2= 6,7,16,17,20,21 -hexahydro-15H, 19H-18-methyl-dibenzo[e,r][1,4,8,12,16]dioxatriazacyclonona-decine) was obtained as an orange-red microcrystalline solid. Complexes (2) and (5) have been analytically and spectroscopically characterized.
