“…The Mo−Mo bond distances of ∼2.10 Å are in agreement with those of the quadruply bonded Mo 2 cores in similar ligand environments (Xiao et al., 2013, Shu et al., 2014, Tan et al., 2017). The Mo−N, Mo−O, and Mo−S bond lengths in these complexes are comparable with those in the thiooxamidate (Cotton et al., 2007) and thiooxalate (Tan et al., 2017) bridged analogues. In [ thi- ( NS) 2 ] and [ thi- ( OS) 2 ], the chelating atoms N(O) and S on the bridging ligands are positioned in cis arrangement with respect to the thienylene bridge (Figures 3A–3C), unlike the phenylene bridged analogues, which have the different chelating atoms of the bridging ligands in trans positions (Xiao et al., 2013, Shu et al., 2014).…”
