Two unprecedented three-dimensional ruthenium(II) complexes I and II derive
d from 2-methyl-5-oxo-7-phenyl-3-thioxo-3,4,5,6 tetrahydro-2H-1,2,4-triazep
ine (HTAZO) and 2-methyl-7-phenyl-3,5-dithioxo-3,4,5, 6-tetrahydro-2H-1,2,4
-triazepine (H(2)TAZS) have been prepared by the reaction of these triazepi
nes with [Ru(p-cymene)Cl-2](2) in the presence of triethylamine. NMR spectr
oscopic and X-ray diffraction studies of the structures of the resulting co
mplexes reveal different behavior of HTAZO and H(2)TAZS in the coordination
process. (C) 2001 Published by Elsevier Science B.V. All rights reserved.
