An organotin( II ) anion with three η 5 ‐Cp ligands and a Sn atom in a trigonal‐planar environment are found in the title compound 1 (see diagram), obtained from the reaction of CpNa, [Cp 2 Sn], and PMDETA (mol ratio 1:1:1). This [Cp 3 Sn] − ion is linked to the Na + ion by a μ‐η 5 ‐Cp bridge. Compound 1 is a polymeric array in the solid state due to intermolecular C(H) … Na interactions. PMDETA = (Me 2 NCH 2 CH 2 ) 2 NMe.
