Two nearly isoformular isomeric dinuclear Platinum(II) complexes with planar and butterfly [Pt-2(mu(2)-S)(2)] core structures
Two dinuclear Pt-II complexes bearing fluorinated phosphine and thiolate ligands were synthesized from mononuclear starting materials, and characterized. Complex [(PPh2(C6F5))(SC6F5)Pt(mu(2)-SC6F5)(2)Pt(SC6F5)(PPh2(C6F5))] has phospine ligands arranged trans and presents a planar [Pt-2(mu(2)-S)(2)]...

| Resumo: | Two dinuclear Pt-II complexes bearing fluorinated phosphine and thiolate ligands were synthesized from mononuclear starting materials, and characterized. Complex [(PPh2(C6F5))(SC6F5)Pt(mu(2)-SC6F5)(2)Pt(SC6F5)(PPh2(C6F5))] has phospine ligands arranged trans and presents a planar [Pt-2(mu(2)-S)(2)] core structure, imposed by symmetry. In contrast, the almost isoformular complex [(PPh(C6F5)(2))(SC6F5)Pt(mu(2)-SC6F5)(2)Pt(SC6F5)(PPh(C6F5)(2))] revealed to be a butterfly molecule with phosphine ligands in a cis configuration. In both complexes, two pentafluorobenzenethiolate ligands bridge metal centers in an anti conformation. Both compounds have been X-ray characterized. Trans complex: a = 11.8576(13) angstrom, b = 12.3237(14) angstrom, c = 13.4644(16) angstrom, alpha = 90.528(9)degrees, beta = 113.866(9)degrees, gamma = 107.698(9)degrees, P (1) over bar |
