Abstract Reactions of the n ‐propyl‐bridged diaminotroponimine H 2 {( i Pr)TP} with dialkylzinc compounds in toluene lead, depending on the stoichiometric ratio, either to dimetallic singly bridged products of composition [(RZn) 2 {( i Pr)TP}] [R = Me ( 1 ), Et ( 2 )] or to dimetallic doubly bridged helical products of composition [Zn{( i Pr)TP}] 2 ( 3 ). Compound 3 , which was characterised by single‐crystal diffraction methods, is the first bridged aminotroponiminate complex in which a helical structure is observed. (© Wiley‐VCH Verlag GmbH & Co.
