Homologous compounds of the linalool type R(CH3)2El-OH (with R=C6H5CH2 and C6H5CH2CH2) as well as their derivatives R(CH3)2El-OCH3 and 2O show, in dependence of El=C, Si, Ge and Sn partly similar, but sometimes very different characteristics of odor.Unexpected are high qualities of fragrance with El=Ge, whereas derivatives with El=Sn remain scentless, obviously owing to polymerization.Noteworthy are the strong differences of odor in the system C6H5CH2El(CH3)3 from C via Si and Ge up to Sn, standing fully contrary to the postulation of Amoore whereupon smell qualities are only controlled by size and shape of molecules.C6H5CH2Sn(CH3)2OH(A1Sn) crystallizes as poly-μ-hydroxo-benzyldimethyltin with an one dimensional Sn-O-Sn-O chain (Sn-O 2.17(9) and 2.29(9) Angstroem) in the monoclinic space group C2 (a=12.696(4), b=4.181(2), c=10.626(3) Angstroem and β=106.8(3) deg).
