Two nitratocomplexes of organotin compounds [Sn(NO 3 ){(C 6 H 5 ) 3 Sn}] and [Sn(NO 3 ){(C 6 H 5 ) 3 Sn} 3 ] have been synthesized and their i.r. spectroscopic properties and X‐ray structures have been studied. Crystals of both compounds are monoclinic (space group P2 1 /c with unit cell dimensions: a = 10.42(1), b = 18.91(2), c = 9.09(1) Å, β = 98.3(1)°, Z = 4 for the first compound; space group P2 1 /n with unit cell dimensions: a = 19.153(8), b = 13.957(6), c = 17.914(8) Å, β = 95.8(1)°, Z = 4 for the second compound). The structures have been solved by X‐ray analysis and refined by least‐squares techniques. The main structural features are the presence of tin‐tin bonds in both compounds and of a tetranuclear system of tin atoms in the second one.
