fac-Re(CO) < inf > 3 < /inf > -based organometallic supramolecular coordination complexes using thiophene motif decorated flexible ditopic benzimidazolyl donor

Abstract

Thiophene/bithiophene units decorated flexible ditopic benzimidazolyl donors (Ln) were synthesized. Neutral, heteroleptic, dinuclear rhenium(I)-based organometallic supramolecular coordination complexes (SCCs) (1–4) were synthesized using Ln, Re2(CO)10 and tetrahydroxy-p-benzoquinone via one-step procedure. All the molecules were characterized by various methods. SCCs 1, 2 and 4 were further analyzed by X-ray analysis. All the ligands and the complexes are emissive at room temperature.
