    Bis(1-methylboratabenzene)lead, Pb(C5H5BMe)(2) (1), was synthesized by the reaction of Li(C5H5BMe) with PbCl2 as a low-melting (mp 60 degrees C) thermochromic yellow crystalline solid (63%). The lighter homologues Sn(C5H5BMe)(2) (2) and Ge(C5H5BMe)(2) (3) were obtained from 1-methyl-2-(trimethylstannyl)-1,2-dihydroborinine, 2-(Me3Sn)C5H5BMe, and SnCl2 and GeI2, respectively, as colorless liquids (70%). The plumbocene analogue 1 possesses a monomeric bent-sandwich structure with a bending angle of 135.2(3)degrees. Compound 1 forms addition compounds with nitrogen bases such as 1.TMEDA (6) and 1.bipy (7). Adduct 7 has a bent-sandwich structure with the 2,2'-bipyridine ligand in the pseudoequatorial plane; the bending angle is 139.1.(5)degrees.

    AbstractAusgehend von 2‐(Me3Sn)C5H5BMe und InMe3 wurde der neue Boratabenzol‐Komplex InMe(C5H5BMe)2 erhalten. Die Verbindung zeigt in Lösung auf der NMR‐Zeitskala eine fluktuierende Struktur mit effektiver C2v‐Symmetrie. Die Kristallstrukturanalyse zeigt, daß im Festkörper vier Moleküle in der asymmetrischen Einheit vorliegen, die sich vorwiegend in der Bindung des Metallatoms an die insgesamt acht symmetrieunabhängigen Boratabenzol‐Liganden unterscheiden. Das in Lösung dynamische Verhalten findet im Kristall seine Entsprechung in weichen Strukturparametern bezüglich der Indium‐Ring‐ligand‐Koordination, deren Variabilität die Standardabweichungen der Einzelbeobachtung um eine Größenordnung übersteigt.
