The XAS model of the square planar {[Cu(Im)4(Oax1)](Oax2)}2+ complex ion and eight second shell solvent waters. The imidazole rings are staggered, approximately alternating between the xy- and yz-planes. The −z distant axial oxygen scatterer is directly below the copper. Only the proximal atoms of the axial scatterers could be detected. See the text for details.
