Tetrakis(trimethylstannyl) germanium was prepared and studied by 1 H, 13 C, 73 Ge and 119 Sn NMR spectroscopy. Quadrupolar relaxation of the 73 Ge nucleus is slow, which allows one to measure 1 J 117/119 Sn, 73 Ge D 37 Hz and to determine its positive sign by a 2D heteronuclear 73 Ge-1 H shift corr

## Abstract The empirical Karplus‐type dependence of ^3^__J__(^119^Sn,^13^C) and ^3^__J__(^119^Sn,^1^H) couplings in organotin(IV) derivatives has been computationally validated by DFT methods both at the non‐relativistic and scalar ZORA relativistic level. A preliminary calibration of the computat
The 13C chemical shifts and 'J 119Sn-13C values for trimethyl tin chloride in 22 solvents are reported. Linear correlation analysis of 'J with the solvatochromic parameters I[\* and fi gave only a fair correlation (r = 0.960). A better correlation was obtained for the 13C chemical shift with n\* and
