The enantiomerically pure ligand L3RR (2R,3R)-bis(2,2′-dipyridyl-5-methoxyl)butane has been synthesised by linking two 2,2′-bipyridine units with (2R,3R)-butandiol. The reaction of L3RR with Zn(II) afforded a mononuclear species and the 1H NMR spectroscopy points to a C1 symmetry, expected for a distorted trigonal bipyramidal coordination environment. These observations were confirmed by MM2 calculations
