Formation of a tetrahedral WC3 framework from a cyclic WC3(tungstenacyclobutadiene) system via attack on tungsten by nitrogen-doner ligands: X-ray study of W[C3Me2(But)][Me2N(CH2)2NMe2]Cl3
Abstract
The tungstenacyclobutadiene complex W[C3Me2(But)]Cl3 reacts with Me2N(CH2)2 NMe2 to form the 1:1 adduct W[C3Me2(But)][Me2N(CH2)2 NMe2]Cl3; a single-crystal X-ray diffraction study of this product shows it to possess a ‘tungstenatetrahedrane’-like core with short W–C distances[2.040(7),2.115(7), 2.133(7)Å].
