Reference of 254-60-4, Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. 254-60-4, Name is 1,8-Diazanaphthalene,introducing its new discovery.
The reactions of with several nitrogen-containing heterocycles under thermal conditions have been studied. 1H-Pyrrolo<2,3-b>pyridine (Hppy) and benzimidazole (Hbzim) give the trinuclear clusters (1a) and (2a), respectively.However, benzotriazole (Hbztz) affords the dinuclear complex (3a). 1,8-Naphthyridine(napy) produces the carbonyl-bridged cluster (4).Copmlex (4) reacts with HBF4 to give the cationic complex (5) which has all terminal carbonyls.Complex (5) regenerates complex (4) on reaction with NEt3. 1,10-Phenantrhroline(phen),2,2′-biquinoline(biquin) or 2,2′-bipyrimidine(bipym) react with to give , in which the L-L ligand chelates one ruthenium, and two carbonyl groups bridge the same edge of the triangle.The structures of compounds (1a) and (4) have been established by X-ray diffraction studies.Complex (1a) crystallizes in the monoclinic space group P21/a with a = 14.688(5), b = 16.251(7), c= 8.594(5) Angstroem, beta = 97.64(2) deg, and Z = 4.Crystals of (4) are monoclinic, space group P21/c with a = 15.374(7), b = 17.336(6), c = 16.167(7) Angstroem, beta = 98.02(3) deg, and Z = 8.Both structure were solved from diffractometer data by direct and Fourier methods and refined by full-matrix <(1a)> and block-matrix <(4)> least-squares to R = 0.0349 for 3211 observed reflections for (1a) and to R = 0.0405 for 4205 observed reflections for (4).In(1a) the pyrrolopyridinate ligand is co-ordinated to three Ru atoms, through the pyridinic N-atom to one metal and through the pyrrolic N atom symmetrically bridging the other two, which are involved also in a hydridic bridge.In (4) there are two independent, but very similar, complexes in which three carbonyls bridge the three edges of a triangular metal array; the 1,8-naphthyridine ligand bridges two metal atoms through the two N atoms.
