Crystal structure of bis(N-tert-butylbenzamidinium) hexachloridozirconate(IV) dichloromethane disolvate

Abstract

In the ZrIV complex anion of the title complex salt, [(C4H9)HNC(C6H5)NH2]2[ZrCl6]·2CH2Cl2, the ZrIV cation, located on an inversion centre, is coordinated by six Cl− anions in a distorted octahedral geometry with Zr—Cl distances in the range 2.433 (2)–2.4687 (19) Å; in the amidinium cation, the dihedral angle between the aromatic ring and [NCN] plane is 43.3 (4)°. In the crystal, the amidinium cations and [ZrCl6]2− anions are linked by N—H...Cl hydrogen bonds, forming a two-dimensional network extending along the b axis; two dichloromethane solvent molecules are linked by a pair of weak C—H...Cl hydrogen bonds, forming a centrosymmetric [CHCl]2 six-membered ring.
