摘要：

The reaction of [(n-C4H9)4N][TcOCl4] with N,N'-ethylenebis(2-phenoxyacetamide), H4epa, in methylene chloride, yields orange crystals of [(n-C4H9)4N][TcO(epa)]. The X-ray structure reveals an oxotechnetium(V) core with the oxo group occupying the apical position of a distorted square pyramid whose base is defined by the oxygen and nitrogen donors of the quadruply deprotonated ligand. Crystal data: triclinic space group, P1BAR, with a = 12.067(3), b = 12.110(4), c = 12.289(3) angstrom, alpha = 109.59(1), beta = 111.11(1), gamma = 92.09(1)-degrees, V = 1656.4(3) angstrom 3, Z = 2, D(calc) = 1.34 g cm-3. Structure solution and refinement based on 4177 reflections with F(o) greater-than-or-equal-to 6-sigma(F(o)) converged at R = 0.039.
