Full title: Reactions of the technetium(I) carbonyl complexes [Tc(PMe2Ph)3(CO)2Cl] and [Tc(PPh3)2(CO)3Cl] toward pseudoallyl ligands such as triazenido, formamidinato, and acetamidinato. Crystal structures of [Tc(PMe2Ph)2(CO)2(p-CH3C 6H4N..-N..-NC6H 4CH3-p )] and [Tc(PMe2Ph)2(CO)2(C6H 5N..-C(CH3)..-NC6H 5)]. New technetium(I) complexes of bidentate pseudoallyl ligands as triazenido, formamidinato, and acetamidinato have been synthesized and characterized. X-ray structure determinations of [Tc(PMe2Ph)2(CO)2(p-CH3C 6H4N..-N..-NC6H 4CH3-p)] (1a) and [Tc(PMe2Ph)2(CO)2(C6H 5N..-C(CH3)..-NC6H 5)] (1c) show the technetium atom in a distorted octahedral coordination geometry with two axial PMe2Ph and two cis-CO groups and the chelate ligands, which form a four-membered ring with the metal. Compound 1a crystallizes in space group Pbca of the orthorhombic system with a = 11.036 (2) ?, b = 14.657 (4) ?, c = 38.92 (1) ?, and R = 0.045 for 3381 diffractometer data with I ≥ 3σ(I). Compound1Ic crystallizes in the same space group, Pbca, with a = 8.954 (3) ?, b = 16.727 (2) ?, c = 41.435 (5) ?, and R = 0.035 for 4108 diffractometer data with I ≥ 3σ(I).
