The interactions of the heteroallenes CO2, OCS, and CS 2 with (Me2N)2Sn have been investigated. These CX2 species insert into the Sn-N bonds under mild conditions to provide products bis-(N,N-dimethylcarbamato)tin(II), [(Me2NCO 2)2Sn]2, bis-(N,N-dimethylthiocarbamato)tin(II) , [Me2NC(O)S]2Sn and bis-(N,N-dimethyldithiocarbamato) tin(II), (Me2NCS2)2Sn. These molecules have been fully characterized by traditional spectroscopic methods as well as by X-ray crystallography. The [Me2NC(O)S]2Sn product is the first example of a structurally characterized Sn(II) thiocarbamate. The solid-state structures of the final products vary depending on the heteroallene inserted. The CO2-inserted product is dimeric in the solid-state, with both bridging and chelating carbamate ligands. These dimers form a chain-like network via intermolecular Sn...O interactions. The monomeric thiocarbamate also shows a chain-like extended structure, through both Sn...O and Sn...S interactions, while the dithiocarbamate product has no significant intermolecular contacts.
