Crystal structure of bis-(N-tert-butyl-benzamidinium) hexa-chlorido-zirconate(IV) di-chloro-methane disolvate.

ABSTRACT

In the Zr(IV) complex anion of the title complex salt, [(C4H9)HNC(C6H5)NH2]2[ZrCl6]·2CH2Cl2, the Zr(IV) cation, located on an inversion centre, is coordinated by six Cl(-) anions in a distorted octa-hedral 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 di-chloro-methane solvent mol-ecules are linked by a pair of weak C-H⋯Cl hydrogen bonds, forming a centrosymmetric [CHCl]2 six-membered ring.
