Experimental and experimental-theoretical topological characteristics of the electron density distribution in the crystal of NCN-(2-pyridinecarbonitrile)-(3,6-di-tert-butylcatecholato)triphenylantimony(v)

Experimental and experimental-theoretical studies (the invariom approach, whole-molecule aspherical scattering factors) of the electron density distribution were carried out to compare its topological characteristics at the critical points (3, −1) of the NCN-(2-pyridinecarbonitrile)-(3,6-di-tert-butylcatecholato)triphenylantimony(v) complex. The topological characteristics of the electron density distribution at the critical points (3, −1) and the atomic volumes determined in experimental studies are almost in quantitative agreement with the results of experimental-theoretical investigation.
