Figure 2
Schematic representation and CCF of (a) neodymium, (b) copper and (c) rhenium (bottom) complexes in the structures of Na3[Nd(Pydc)3]·14H2O (I), [Cu(Pydc)(Pyca)]·2H2O (FEKYIE; Brandi-Blanco et al., 2005) and [Re2(Pydc)((PPh2)CH2(PPh2))2Cl2]·C6H6 (IQAMUI; Chattopadhyay et al., 2003). Metal atoms are depicted as empty circles, coordination bonds are shown as dotted lines, O atoms are depicted as black circles, N atoms – as grey circles, and P and Cl atoms are labeled. |
