Title: Effect of ring size on properties of technetium amine oxime complexes. X-ray structure of TcO/sub 2/Pent(AO)/sub 2/, which contains an unusual eight-membered chelate ring, and TcOEn(AO)/sub 2/

Abstract

A series of neutral technetium(V) complexes have been synthesized (TcO(AO)/sub 2/, TcOEn(AO)/sub 2/, TcO/sub 2/Bn(AO)/sub 2/, and TcO/sub 2/Pent(AO)/sub 2/) in which the length of the hydrocarbon backbone of the amine oxime ligand is varied to effect chemical changes in the resultant complexes. Pn(AO)/sub 2/, 3,3,9,9-tetramethyl-4,8-diazaundecane-2,10-dione dioxime, is the prototype for these ligands. In this series of technetium(V) complexes in which the overall ring size is varied, both monooxo and trans-dioxo cores are observed, and an unusual eight-member chelate ring with the technetium(V) center is found with TcO/sub 2/Pent(AO)/sub 2/. TcO/sub 2/Pent(AO)/sub 2/ x CHCl/sub 3/, TcCl/sub 6/O/sub 4/C/sub 17/H/sub 33/, crystallizes in the triclinic system, space group P anti 1, with a = 1.418 (2) A, b = 13.940 (7) A, c = 18.992 (10) A, ..cap alpha.. = 69.29 (4)/sup 0/, ..beta.. = 90.00 (3)/sup 0/, ..gamma.. = 83.69 (3)/sup 0/, and Z = 4. TcOEn(AO)/sub 2/, TcO/sub 3/N/sub 4/C/sub 12/H/sub 23/, crystallizes in the orthorhombic system, space group Pbca, with a = 11.581 (2) A, b = 12.596 (4) A, c = 21.155 (3) A, and Z = 8.
