Crystal Structure of Binuclear Terephthalato-bridged Manganese(III) Complex with 2-(2′-Hydroxyphenyl)oxazoline Analog

Abstract

The title compound, [Mn₂(Lox)₄(H₂O)₂(μ-tpa)]·2CH₃OH·4H₂O, [HLox = 4,6-dimethyl-3-(4,4-dimethyl-2-oxazolinyl)-N-(2-hydroxy-l,l-dimethylethyl)salicylamide, H₂tpa = terephthalic acid], was synthesized and characterized by single-crystal X-ray analysis. The compound crystallizes in the triclinic space group P1 with cell parameters a = 11.964(7)Å, b = 13.419(11)Å, c = 15.167(13)Å, α = 82.91(7)°, β = 89.49(6)°, γ = 70.79(5)°, V = 2280(3)ų, D_calcd = 1.296 g/cm³, Z = 1. The R1 [I > 2σ(I)] and wR2 (all data) values are 0.0514 and 0.1800, respectively, for all 8015 independent reflections. Two manganese(III) units are bridged by terephthalate dianion with a monoatomic coordination mode.
