VENEGAS, FELIPE; PIZARRO, NANCY  y  VEGA, ANDRES. STRUCTURAL AND PHOTOPHYSICAL PROPERTIES OF A MONONUCLEAR Re(I) COMPLEX:[P,N-{(C6H5)2(C5H5N)P}Re(CO)3Br]. J. Chil. Chem. Soc. [online]. 2011, vol.56, n.3, pp. 823-826. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072011000300023.

We have prepared a new monometallic rhenium(I) carbonyl, the complex [P,N-{(C6H5)2(C5H5N)P}Re(CO)3Br] by direct reaction of (Re(CO)3Br(THF))2 and the ligand (C6H5)2(C5H5N)P The structure in the complex shows the pyridinic-phosphine ligand in a chelating mode, occupying cis positions around the rhenium octahedral environment. The molecule displays an absorption band centered at 315 nm which has been assigned to a MLCT transition, and a luminescence quantum yield of 0.001.
