摘要：

The theoretical and experimental study of the ion organisation in crystalline [(eta(6)-C6H6)(2)Cr](+) [CrO3(OCH3)](-) affords a complete picture of the relative contribution to crystal cohesion of Coulombic interactions, pi-stacks, and charge assisted C-H ... O( -) hydrogen bonds while showing the repulsive nature of short C-H ... O contacts between anions.
