title: A zirconium zwitterion containing a caged amine H atom.
abstract: The crystallographically centrosymmetric zwitterion bis[tris(3,5-dimethyl-2-oxidobenzyl-kappaO)ammonium]zirconium(IV) crystallizes as the chloroform disolvate, [Zr(C(27)H(31)NO(3))(2)].2CHCl(3), with the two molecules of chloroform closely associated with two of the aromatic rings. The Zr atom has a distorted octahedral geometry with three phenoxy O atoms from each of the two ligands coordinated to it. Charge balance is maintained by protonation of each N atom, which then forms intramolecular hydrogen-bonding interactions to all three adjacent O atoms.
