Halogen bond preferences of thiocyanate ligand coordinated to Ru(II) via sulphur atom

Halogen bonding (XB) between [Ru(bpy)(CO)2(S-SCN)2] (bpy = 2,2'-bipyridine) and I2 was studied by co-crystallizing the metal compound and diiodine from dichloromethane solution. Halogen bond between Ru coordinated S and I2 was found to be the preferred halogen bond mode. No crystalline XB adduct with I⋯N contact was observed.241
