The Crystal Structures of Triphenylarsin-p-toluene Sulfonylimine and of its Donor-Acceptor Complex [ZrCl4(Ph3AsNSO2Tol)]2The molecular structures of the title compounds are reported. In the donor-acceptor complex [ZrCl4(Ph3AsNSO2Tol)]2 the zirconium atoms are bridged by the oxygen atoms of the triphenylarsin-p-toluene sulfonylimine molecules, forming a centrosymmetric dimer with a puckered Zr2O4S2 eight-membered ring in the chair conformation.Ph3AsNSO2Tol: Space group P1, Z = 2, structure determination with 4 010 observed unique reflections, R = 0.036.

Lattice dimensions at -60°C: a = 1 387.3(4), b = 1 434.9(2), c = 1 404.7(4) pm, β = 92.71(1)°.
Notes:
Es wird über die Molekülstrukturen der beiden Titelverbindungen berichtet. In dem Donor-Akzeptorkomplex [ZrCl4(Ph3AsNSO2Tol)]2 sind die Zirkoniumatome über die O-Atome der Triphenylarsin-p-toluolsulfonylimin-Moleküle zu einem zentrosymmetrischen Dimer mit einem Zr2O4S2-Achtring in der Sesselkonformation verknüpft.Ph3AsNSO2Tol: Raumgruppe P1, Z = 2, Strukturlösung mit 4 010 unabhängigen beobachteten Reflexen, R = 0,036. Gitterkonstanten bei 19°C: a = 897,52(4), b = 1 071,82(6), c = 1 337,49(5) pm, α = 110,280(4)°, β = 98,814(4)°, γ = 109,872(4)°.[ZrCl4(Ph3AsNSO2Tol)]2: Raumgruppe P21/n, Z = 4, Strukturlösung mit 3 762 unabhängigen beobachteten Reflexen, R = 0,078.
