Abstract

The concept of bond order has been extended to Del Re calculations, and the bond orders of tin-chlorine and tin-carbon bonds in Me 4- n SnCl n ( n = 1 to 4) type compounds have been calculated. The tin-chlorine bond order increases progressively from 0.922 in Me 3SnCl to 0.977 in SnCl 4, and correlates satisfactorily with the experimental tin-chlorine bond distances. The tin-carbon bond order, on the other hand, remains almost constant, in agreement with the constancy of tin-carbon bond distance in the series. The average tin-chlorine, tin-carbon and tin-hydrogen stretching frequencies in similar compounds vary linearly with the calculated bond polarities indicating variation in bond polarity to be the dominating factor. The unusually low values of the tin-carbon stretching frequency for the tin-vinyl bond compared to the tin-methyl bond in Me 3ViSn and Et 2Vi 2Sn can also be explained in terms of larger polarity of the tin-vinyl bond in these compounds.
