Oxo[3,3'-(1,3-propanediyldiimino)bis(3-methyl-2-butanone oximato)(3-)-N,N',N'',N''']technetium(V), [TcO(C13H25N4O2)]

Msub(r) = 383.4, monoclinic, Pc, a = 6.950 (4), b = 11.187 (3), c = 11.060 (4) A, β = 104.13 (5)0, V = 833.8 (2) A3, Z = 2, Dsub(x) = 1.527 (1) g cm-3, Mo Kα, lambda = 0.7107 A, μ = 8.56 cm-1, F(000) = 396, T = 295 (1) K, final Rsub(F) = 2.4% for 2601 unique reflections. The Tcsup(V) ion is surrounded by an approximate square pyramid of one multiple-bonded oxygen atom plus four nitrogen atoms from the tetradentate ligand. The distances between the deprotonated N(imino) atoms and the Tc atom [1.917 (3), 1.908 (3) A] are much shorter than the N(oxime)-Tc bond distances [2.086 (3) and 2.093 (4) A]. The Tc atom is 0.678 (1) A from the N4 plane in the direction of the oxo oxygen. (Auth.)
