Quantifying intermolecular interaction of one trinuclear Zn-II and one mononuclear Cd-II complex of pyrimidine based hexadentate Schiff base : Insights from Hirshfeld surface analysis

摘要

The Hirshfeld surface area was evaluated for both the complexes [Zn-3(L)(2)Cl-6] (1) and [Cd(L)(H2O)(2)](ClO4)(2) (2) [L = N-6 donor hexadentate Schiff base 2,4-bis[2-(pyridine-2-ylmethylidene)hydrazinyl]pyrimidine]. The Hirshfeld surface analysis quantify the rare Cl center dot center dot center dot Cl weak interaction in 1 and other molecular interactions e.g. C center dot center dot center dot H, H center dot center dot center dot H, C center dot center dot center dot C, pi center dot center dot center dot pi present in the solid state of both complexes 1 and 2.
