Figure 2
Crystal structure of (I). Ellipsoids are drawn at the 50% probability level; hydrogen atoms are displayed but not labeled. Primed and unprimed atoms are related by an inversion center, which brings the two square-pyramidal Cu(bpy)(C4H4O6) moieties into contact [Cu⋯O1′ = 2.703 (2) Å]. The inset is a schematic illustration of the dimerization. |
