Figure 2 Fragment of the crystal packing diagram of (I) showing the simultaneous multidimensional interlinkage of the central monomeric [Cu(PTA)4]+ unit (black coloured) with twelve neighbouring ones (each represented by different colour) via repeating O10—H10⋯N1 hydrogen bonding interactions (black dashed lines) between crystallization water molecules O10 (coloured balls) and PTA N1 atoms. H and Cl atoms are omitted for clarity. |
