Abstract
Homo-hetero binuclear cationic complexes with the formulation [(η 6-arene)RuCl(μ-dpp)(L)] + (η 6-arene = benzene; L = PdCl 2 ( 1a); PtCl 2 ( 1b), and η 6-arene = p-cymene; L = PdCl 2 ( 2a); PtCl 2 ( 2b)), [(η 6-arene)RuCl(μ-dpp)(L)] 2+(η 6-arene = p-cymene; L = [(η 6-C 6H 6)RuCl] ( 2c), and [(η 6-C 10H 14)RuCl] ( 2d)) were prepared. Molecular structure of the representative homo binuclear complex [{(η 6-C 10H 14)RuCl}(μ-dpp){(η 6-C 10H 14)RuCl}](PF 6) 2 ( 2d) was determined crystallographically. Weak interaction studies on the complex 2d revealed stabilisation of the crystal packing by weak inter and intra molecular C–H⋯X (X = F, Cl, π) and π–π interactions. The C–H⋯F interactions lead to parallel helical chains and encapsulation of counter anion in self-assembled cavity arising from C–H⋯π and π–π weak interactions.
