Tetramethyl 1,2-bis(2-aminophenoxy)ethane-N,N,N',N'-tetraacetate

M. Rademeyer, D. A. Barkhuizen and G. E. M. Maguire

Abstract: In this crystal structure, the methyl derivative of the BAPTA (bisaminophenol tetraacetic acid) ligand, C₂₆H₃₂N₂O₁₀, exhibits two molecular geometries. The asymmetric unit consists of one and one-half molecules. One molecule is located on a centre of inversion. The other has an interesting conformation between that of the first, and the geometry observed in a complex of a similar ligand.
