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.
