Synthesis, Structure, and Bonding of Group 8 Transition Metal Germyl Complexes, [Cp*M{κ²-Ge,S-GeCl₂C₇H₄NS₂}(PPh₃)] (M = Ru or Os)

Abstract

The hemilabilty of 1,3-S,N-chelated transition metal (TM) complexes [Cp*M{κ 2 -S,N-C 7 H 4 NS 2 }(PPh 3 )] (Cp* = η 5 -C 5 Me 5 ) (1a: M = Ru and 1b: M = Os) allows them to capture GeCl 2 to generate TM−germyl complexes [Cp*M{κ 2 -Ge,S-GeCl 2 C 7 H 4 NS 2 }(PPh 3 )] (2a: M = Ru and 2b: M = Os).Based on the structural parameters, these complexes can be described as tethered germyl complexes. To investigate the bonding modes of these complexes, density functional theory (DFT) computations were carried out.
