Description
Summary:Molecular structures of two bis(ZnIIdioxolene) complexes are described:  (Tp Cum,Me Zn) 2 1-H 2 (C106H123.50B2N12O10Zn2), tetragonal, P4/ncc, a = 25.1810(2) Å, b = 25.1810(2) Å, c = 34.7744(2) Å, α = 90°, β = 90°, γ = 90°, Z = 8; (Tp Cum,Me Zn) 2 1-H (C101H120B2N12O6Zn2), triclinic, P1̄, a = 13.6624(2) Å, b = 13.80920(10) Å, c = 26.62340(10) Å, α = 96.6910(10)°, β = 91.8560(10)°, γ = 109.0190(10)°, Z = 2. One of the complexes, (Tp Cum,Me Zn) 2 1-H 2 , has two protonated catecholate ligands, while the other complex, (Tp Cum,Me Zn) 2 1-H, has one protonated catecholate and one semiquinone ligand. When reacted with PbO2, a labile S = 1, bis(ZnIIsemiquinone) complex is formed in which the two semiquinones are attached to a common carbonyl group.
