Abstract

The synthesis and characterization of the tridentate "heteroscorpionate" mixed functionality ligand, (2-thiophenyl)-bis(pyrazolyl)methane, L1, is reported. This ligand was used to synthesize the complexes, [Fe(L1)₂][ClO₄], [Co(L1)₂][BPh₄], and [V(L1)₂][BPh₄]. X-ray crystallographic analysis of the latter two complexes gave the following structural parameters: [V(L1)₂][BPh₄]·MeCN·ⁱPr ₂O, C₅₈H₅₇N₉B₁O₁S ₂V₁, monoclinic, a = 16.197(2) Å, b = 19.281(2) Å, c = 17.985(2) Å, β= 102.343(9)°, space group P2₁/c; [Co(L1)₂][BPh₄]·CH₂Cl₂, C₅₁H₄₂N₈B₁-Cl₂Co ₁S₂, triclinic, a = 12.751(1) Å, b = 12.830(1) Å, c = 14.740(1) Å, α = 98.351(7)°, β= 98.122(6)°, γ = 97.023(8)°, space group P1. An example of the use of this new class of "heteroscorpionate" ligands for systematic comparisons of electronic properties of metal complexes with identical topology that vary only in the nature of one of the donor atoms is given.
