“…Six ligands among the 16 use a trimetallic triconnective bridging mode (κ 3 :µ 2 ‐S, µ‐O) to coordinate exclusively to the copper atoms of the extended butterfly motifs. Interestingly, this is the first time that this bridging mode is observed in monothiocarbonate chemistry; however, this kind of bonding was reported previously in monothiocarbamate (mtc) and monothiocarboxylate complexes, for example, [M(SCONR 2 )] 6 (M = Cu and Ag),[12a], [12b] [Ni(SCONR 2 ) 2 ] 6 ,[12c] and [Cu 4 (SC{O}Ph) 4 (PPh 3 ) 3 ] . Similarly, another two sets of monothiocarbonate ligands use a new tetrametallic tetraconnective (κ 4 : µ 3 ‐S, µ‐O) coordination mode to bridge predominantly to the central square pyramidal Cu atoms (Cu8, Cu6, Cu7, Cu10, Cu11) and the extrapolated copper atoms (Cu5, Cu12) in the butterfly structures.…”
