Ein Triarsanato(1.3)-Chelat des Titans / A Triarsanato(1,3) Chelate of Titanium

Abstract

When the cyclopentaarsane (AsC₂H₅)₆ is reacted in a 1:2 or 1:5 molar ratio with metallic potassium in THF, soluble dipotassium catenaarsanes of the assumed stoichiometry K₂(ASC₂H₅)₅ (1) or K₂(ASC₂H₅)₂ (2), respectively, are formed. On reaction with (C₅H₅)₂TiCl₂ in THF, both the red 1 or the greenish 2 lead to the same dark-brown, airsensitive triarsanato complex (C₅H₅)₂Ti(AsC₂H₅)₃ (3).
