The crystal structure of (AsPh(4))(2)[Re(NO)(H2O)(CN)(4)]. 5H(2)O has
been determined from three-dimensional X-ray diffraction data. The [Re
(NO)(H2O)(CN)(4)](2-) ion has a distorted octahedral geometry with the
following bond distances: Re-NO = 1.732(7), Re-OH2 = 2.165(5) and Re-
CNav = 2.09 Angstrom. The NO group bond is at 178.4(7)degrees to the r
henium atom and N-O = 1.181(8) Angstrom. The rhenium atom is displaced
by 0.17 Angstrom out of the plane formed by the four carbon atoms of
the cyano ligands towards the nitrosyl ligand.
