Seven bis(organostannyltetrazoles), R3SnN4C-X-CN4SnR3 (R = Et, Bu or Pri; X = 1,2-, 1,3- or 1,4-C6H4), have been synthesised by a cycloaddition reaction involving SnR3N3 and NC-X-CN. All of the products formed incorporate a trans-N2SnC3 stereochemistry about tin, though the co-ordination mode of the tetrazole has been found to vary in the combinations of ligating nitrogen atoms used. The crystal structure of 1,3-(2-Bu3SnN4C)2C6H 4·2MeOH showed that the preferred co-ordination site for tin on the tetrazole is the less-hindered N2 position. The crystal structures of 1,2-(2-Et3SnN4C)2C6H4 and 1,2-(2-Bu3SnN4C)2C6H4, respectively showed that these compounds are either two- or three-dimensional supramolecular arrays, the arrangements of which are dictated by the organic groups on tin.
