Description / Table of Contents:
Compounds of Germanium and Tin. 17 [1]. Alkylarylstannylene Complexes of Chromium and Molybdenum without Donor StabilizationReaction of the complexes [(OC)5M(THF)], M = Cr, Mo, with the alkylarylstannylene RR′Sn: R = 2,4,6-tBu3C6H2, R′ = CH2C(CH3)2-3,5-tBu2C6H2, provides the donor-free stannylene complexes [(OC)5Cr=SnRR′] (6) and [(OC)5Mo=SnRR′] (8), respectively. The X-ray structure analyses of the isotypic compounds 6 and 8 reveal the three coordinate tin atoms in strictly planar environments and acute CSnC angles of 91.2° (6) and 91.3° (8).
Notes:
Umsetzungen der Komplexe [(OC)5M(THF)], M = Cr, Mo, mit dem Alkylarylstannylen RR′Sn:, R = 2,4,6-tBu3C6H2, R′ = CH2C(CH3)2-3,5-tBu2C6H2, ergibt die donorfreien Stannylenkomplexe [(OC)5Cr=SnRR′] (6) und [(OC)5Mo=SnRR′] (8). Die Röntgenstrukturanalysen der isotypen Verbindungen 6 und 8 zeigen das Vorliegen planar umgebener dreifach koordinierter Zinnatome mit spitzen CSnC-Winkeln von 91,2° (6) und 91,3° (8) an.
