The crystal structure of the tetranuclear organotin compound 1,1,3,3,5,5,7,7‐octabutyl‐7‐(( E )‐2‐cyano‐3‐{9‐[2‐(2‐methoxyethoxy)ethyl]‐9 H ‐carbazol‐3‐yl}prop‐2‐enoyloxy)‐4,8‐dimethyl‐2,4,6,8‐tetroxa‐1,3,5,7‐tetrastannatricyclo[4.2.0.0 2,5 ]oct‐3‐yl ( E )‐2‐cyano‐3‐{9‐[2‐(2‐methoxyethoxy)ethyl]‐9 H ‐carbazol‐3‐yl}prop‐2‐enoate, [Sn 4 (C 4 H 9 ) 8 (C 21 H 19 N 2 O 4 ) 2 (CH 3 O) 2 (μ 3 ‐O) 2 ], consists of a core of three fused Sn 2 O 2 rings. The central ring consists of two Sn atoms each coordinated by two n ‐butyl chains, two μ 3 ‐bridging O atoms and one μ 2 ‐bridging methanolate O atom. The peripheral Sn 2 O 2 rings consist of one of the central ring Sn atoms, and an Sn coordinated by one μ 3 ‐bridging O atom, one μ 2 ‐bridging methanolate O atom, two n ‐butyl chains and the carboxylate O atom of a ( E )‐2‐cyano‐3‐{9‐[2‐(2‐methoxyethoxy)ethyl]‐9 H ‐carbazol‐3‐yl}prop‐2‐enoate ligand ( L ). Despite an apparent centrosymmetric nature, the complex does not crystallize about an inversion centre. The structure packs with π–π interactions between carbazole moieties on adjacent molecules.
