Abstract: | Summary The crystal structure of the tetraethylammonium salt of ReO(H2O)(CN)4]– has been determined from threedimensional x-ray diffraction data. The light blue crystals are monoclinic, space group P21/m witha=8.760(1),b=9.518(5),c=11.718(1) Å, =102.63(1)o with two molecules per unit cell. The final R value using 2009 observed reflections and anisotropic thermal parameters for all the non-hydrogen atoms was 0.038. The ReO(H2O)(CN)4]– ion has a distorted octahedral geometry with the rhenium atom displaced by 0.30 Å out of the plane formed by the four carbon atoms of the cyano ligands towards the oxo ligand. Bond distances: Re=O=1.667(8), Re–OH2=2.142(7) and Re–C (average)=2.11(1) Å. |
