The structure of (μ-1κ:2(η),κ ,'-(2-{[2,6-bis(propan-2-yl)phen-yl]aza-nid-yl}eth-yl)[2-(1-inden-1-yl)eth-yl]aza-nido)(1,4,7,10,13,16-hexa-oxa-cyclo-octa-dec-ane-1κ )lithiumtin, [LiSn(CHO)(CHN)], at 100 K has monoclinic (2/) symmetry. Analysis of the coordination of the Sn to the indenyl ring shows that the Sn inter-acts in an η 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 cyclo-penta-dienyl ligands and their derivatives.
