Figure 1
(a) and (b) Two views of the structure of MIL-53(Fe)[pyridine] showing the hydrogen-bond interaction between the pyridine and framework hydroxyl as a dotted line in (b) (crystal data taken from Millange et al., 2010BB25), and (c) and (d) Co(BDC)(PNO) (crystal data taken from Munn et al., 2013BB30). (a) and (c) show views parallel to single diamond-shaped channels that form part of the extended structure. Grey spheres are C, red O and cyan N, while the blue polyhedra represent both Fe- and Co-centred octahedral. H atoms are omitted for clarity.  [article HTML]
