Abstract
Asymmetric Re(V) oxo complexes of the type cis-[ReO(Y) (acac 2en/pn)] (Y = CN-, NCS-) were generated from the symmetric precursors trans-[ReO(X)(acac2en/pn)]0/+ (X = H2O, Cl-) by reaction with cyanide and thiocyanate. The products were characterized using standard spectroscopic methods, elemental analyses and single crystal X-ray diffraction. The crystallographic data for the structures reported are as follows: cis-[ReO(NCS)(acac2pn)] (H 20C14N3O3SRe), 1, monoclinic (P21/n), a = 8.0047(6) Å, b = 13.6118 (10) Å, c = 30.597(2) Å, β = 96.571(1)°, V = 3311.9(4) Å3, Z = 8; cis-[ReO(CN)(acac2pn)] (H20C14N 3O3Re), 2, monoclinic (P21/n), a = 9.5139(12) Å, b = 14.0625(18) Å, c = 12.2343(3) Å, = 107.286 (2)°, V = 1562.9(3) Å3, Z = 4; cis-[ReO(NCS)(acac2en)] (H18C13N3 O3SRe), 3, monoclinic (P21/c), a = 17.1965(19) Å, b = 12.7416(14) Å, c = 15.7270(17) Å, = 110.589(2)°, V = 3225.9(6) Å3, Z = 8.
