A distinct tetradentate N2O2-type ligand: (o-Carboranyl)bis(2-hydroxymethyl)pyridine

A new chiral racemic ligand (o-carboranyl)bis(2-hydroxymethyl)pyridine oCB(hmpH)2, that is composed of a central o-carborane unit where two arms radiate out of the cluster carbons each one containing a 2-pyridylmethylalcohol chelating arms, provides two potentially bidentate {NO} or one tetradentate...
