Table 1. Chlorine nqcc's in (CH3)3SnCl (MHz).  Calculation was made on the PBE1PBE/TZV(3df,3p)/def-2-TZVP(Sn) optimized structure with ro(SnCl) [1].
   










Calc *
Expt. [1]
   





35Cl eQq - 36.82 - 35.7747(22)
 
37Cl eQq - 29.02 - 28.2109(15)
 


 







* Method: B1LYP/TZV(3df,3p)/def-2-TZVP(Sn)
The difference between calculated and experimental 35Cl nqcc's is 1.05 MHz (2.9 %).  For 37Cl, the difference is 0.81 MHz (2.9 %).
   

 
Table 2. (CH3)3SnCl  Heavy atom structure parameters (Å and degrees), PBE1PBE/TZV(3df,3p)/def-2-TZVP(Sn) optimized structure, but with ro(SnCl) [1] rather than the optimized value of 2.3626 Å.  Complete structure is given here in Z-marix format.
