Abstract :
The structure of (μ-1κN:2(η2),κ2N,N′-(2-{[2,6-bis(propan-2-yl)phenyl]azanidyl}ethyl)[2-(1H-inden-1-yl)ethyl]azanido)(1,4,7,10,13,16-hexaoxacyclooctadecane-1κ6O)lithiumtin, [LiSn(C8H16O4)(C25H31N2)], at 100 K has monoclinic (P21/n) symmetry. Analysis of the coordination of the Sn to the indenyl ring shows that the Sn interacts in an η2 fashion. A database survey showed that whilst this coordination mode is unusual for Ge and Pb compounds, Sn displays a wider range of coordination modes to cyclopentadienyl ligands and their derivatives.
