Pairs of ligand bridges link the complex units, forming chains which extend along [111] and are inter-associated through Owater—H...N hydrogen bonds, giving a two-dimensional network structure parallel to (001). Weak π–π stacking interactions between the benzene and imidazole rings are also present [minimum ring centroid separation = 3.691 (4) Å].

Orbital Analysis

A new asymmetrical Schiff base ligand, N1-(3-((pyridin-2-ylmethylene)amino)propyl)ethane-1,2-diamine, and its copper(II) complex, [Cu(PPEA)Br]Br·H2O (1), have been prepared. The copper complex has an elongated square pyramidal geometry with a CuN4Br environment. The thermodynamic stability of the compounds and their charge distribution patterns were studied by Density Functional Theory and natural bond orbital analysis. The ability of the ligand and its copper complex to interact with 10 selected biomacromolecules (BRAF kinase, CatB, DNA gyrase, HDAC7, rHA, RNR, TrxR, TS, Top II and B-DNA) was investigated by docking studies and compared with that of doxorubicin.
