Mixed-Ligand Complexes of Technetium. XIV. Structure of trans-[TcCl2(NCS)(Me2PhP)3]
摘要:
mer-[TcCl3(Me(2)PhP)(3)] reacts with potassium thiocyanate with the replacement of only one Cl- ligand by NCS- and forms selectively (OC-6-12)-dichlorotris(dimethylphenylphosphine)(thiocyanato-kappa N)-technetium(III) {mer, trans-[TcCl2(NCS)(Me(2)PhP)(3)]}. No evidence could be found for the formation of the cis analogue, The title compound crystallizes in monomeric units. The Tc atom is coordinated in a distorted octahedral manner with the two Cl ligands in trans positions to each other. The NCS- ligand is N-bonded with a Tc-N bond length of 2.104 (3) Angstrom.
