Abstract

The multitopic heterofunctional pro-ligand 4-[(E)-(1H-imidazol-2-yl)diazenyl]benzoic acid (H′HL) was synthesized by diazotization of 4-aminobenzoic acid followed by coupling with imidazole. Reactions of H′HL (where H=imidazole proton and H′=carboxylic acid proton) with the triorganotin precursors n Pr3SnCl, (n Bu3Sn)2O and Ph3SnOH provided three hypercoordinated triorganotin complexes, viz., [n Pr3Sn(μ4 -L)Snn Pr3]n⋅1/8nEtOH (1), [ n Bu3Sn(μ-HL)]n (2) and [Ph3Sn(HL)]⋅0.5C6H6 (3), with complex 2D and 3D frameworks based on Sn−O, O→Sn, Sn−N and N→Sn metal–ligand bonds as well as N−H⋅⋅⋅N, N−H⋅⋅⋅O and π-interactions. The compositions and structures of 1–3 in solution and in the solid-state were unambiguously established by NMR (1 H, 13C, 119Sn) and IR spectroscopy, UV‒Vis spectral analysis, high-resolution mass spectrometry (HRMS) and single-crystal X-ray difraction (scXRD) studies accompanied by Hirshfeld surface maps and 2D fngerprint plots.
