Here we would like to present interconnection between the experimentally accessible data and the structural parameters. We focus on the indirect spin-spin 13C-13C interaction constants, that represent unique source of information on the electron distribution between involved atoms and reflect the carbon-caron bonding environment. The experimental values of 1J can be correlated to the carbon-carbon bond lenghts and angles, that are accessible by single crystal X-ray crystallography. The theoretical prediction of the nJ(C-C) coupling constants was done using DFT calculation (B3PW91/6-311++G(d,p)) which provides an excellent agreement with the experimental values
