Synthesis, X-ray characterization and DFT studies of N-benzimidazolyl-pyrimidine–M(<scp>ii</scp>) complexes (M = Cu, Co and Ni): the prominent role of π-hole and anion–π interactions

Abstract

Five Cu(<sc>ii</sc>), Co(<sc>ii</sc>) and Ni(<sc>ii</sc>) complexes with 2-(<italic>N</italic>-benzimidazolyl)-pyrimidine and nitrate co-ligands have been synthesized and characterized by X-ray diffraction.
