Bis(tetra-phenyl-arsonium) hexa-chlorido-zirconate(IV) aceto-nitrile tetra-solvate

摘要

The bis-(tetra-phenyl-arsonium) hexa-chlorido-zirconate(IV) salt, (AsPh 4 ) 2 [ZrCl 6 ] (Ph = C 6 H 5 ), was prepared more than 25 years ago [Esmadi & Sutcliffe (1991 ). Indian J. Chem. 30?A , 99–101], but its crystal structure was never reported. By following a similar experimental procedure, the compound was synthesized and its crystal structure was investigated as a aceto-nitrile tetra-solvate, (As(C 6 H 5 ) 4 ) 2 [ZrCl 6 ]·4CH 3 CN, by single-crystal X –ray diffraction. The [ZrCl 6 ] 2? anion adopts a slightly distorted octa-hedral coordination sphere, with Zr—Cl bond lengths of 2.4586?(6), 2.4723?(6), and 2.4818?(5)??, and Cl—Zr—Cl angles ranging from 89.602?(19) to 90.397?(19)°.
