Figure 2From: Synthesis, crystal structures and supramolecular architectures of square pyramidal Cu(II) complexes containing aromatic chelating N,N’-donor ligandsMolecular structures of (1) and (2). (a,b) Crystallographic numbering scheme with displacement ellipsoids drawn at the 50% probability level. The hydrogen atoms are included as spheres of arbitrary radii. (c,d) Hydrogen bonding in between two Cu(II) monomeric units in 1 and 2 respectively.Back to article page
