“…This complex, termed a metalloligand, can itself act as a ligand in a second step, coordinating to a different metal centre leading to the targetted mixed-metal coordination network structure. 2 A number of metalloligands have been previously utilised in this manner, including complexes of pyridinedicarboxylates, 3 Schiff bases 4 and bis(oxamato) ligands, 5 that function as ditopic O-donors, and pyridyl-functionalised porphyrins, 6 dipyrrinato ligands, 7 terpyridines 8 and tris(triazolyl)borates, 9 that function as polytopic N-donors.…”

The iron(III) and aluminium(III) complexes of 1,3-di(4-pyridyl)propane-1,3-dionato (dppd) and 1,3-di(3-pyridyl)propane-1,3-dionato (dmppd), [Fe(dppd)(3)] 1, [Fe(dmppd)(3)] 2, [Al(dppd)(3)] 3 and [Al(dmppd)(3)] 4 have been prepared. These complexes adopt molecular structures in which the metal centres contain distorted octahedral geometries. In contrast, the copper(II) and zinc(II) complexes [Cu(dppd)(2)] 5 and [Zn(dmppd)(2)] 6 both form polymeric structures in which coordination of the pyridyl groups into the axial positions of neighbouring metal centres links discrete square-planar complexes into two-dimensional networks. The europium complex [Eu(dmppd)(2)(H(2)O)(4)]Cl·2EtOH·0.5H(2)O 7 forms a structure containing discrete cations that are linked into sheets through hydrogen bonds, whereas the lanthanum complex [La(dmppd)(3)(H(2)O)]·2H(2)O 8 adopts a one-dimensional network structure, connected into sheets by hydrogen bonds. The iron complexes 1 and 2 act as metalloligands in reactions with silver(I) salts, with the nature of the product depending on the counter-ions present. Thus, the reaction between 1 and AgBF(4) gave [AgFe(dppd)(3)]BF(4)·DMSO 9, in which the silver centres link the metalloligands into discrete nanotubes, whereas reactions with AgPF(6) and AgSbF(6) gave [AgFe(dppd)(3)]PF(6)·3.28DMSO 10 and [AgFe(dppd)(3)]SbF(6)·1.25DMSO 11, in which the metalloligands are linked into sheets. In all three cases, only four of the six pyridyl groups present on the metalloligands are coordinated. The reaction between 2 and AgNO(3) gave [Ag(2)Fe(dmppd)(3)(ONO(2))]NO(3)·MeCN·CH(2)Cl(2)12. Compound 12 adopts a layer structure in which all pyridyl groups are coordinated to silver centres and, in addition, a nitrate ion bridges between two silver centres. A similar structure is adopted by [Ag(2)Fe(dmppd)(3)(O(2)CCF(3))]CF(3)CO(2)·2MeCN·0.25CH(2)Cl(2)13, with a bridging trifluoroacetate ion playing the same role as the nitrate ion in 12.

The Group 13 metal complexes [M(L(2))(3)], where M is Al or Ga and L(2) is 1,3-di(4-pyridyl)-1,3-propanedionato, are hexatopic metalloligands that have been used to prepare mixed-metal-organic frameworks containing interpenetrated primitive cubic networks. In contrast, the europium complex [Eu(HL(2))(3)(H(2)L(2))]Cl(4) x EtOH forms a hydrogen-bonded network following partial protonation of the pyridyl groups.

“…Coordination polymers constitute one of the most important classes of organic‐inorganic hybrid materials, that have been subject of intensive research in recent years . Coordination polymer architectures exhibit potential applications as molecular wires, electrical conductors,, molecular magnets, in host–guest chemistry, and in catalysis . The adsorption of water by porous solids is important for many applications requiring capture and release of water .…”

The solid‐state conversion of a 3D lead(II) coordination polymer, [Pb(1,4‐BDC)(H2O)]n (1) microstructures (1,4‐H2BDC = 1,4‐benzenedicarboxylic acid) with PbO7 coordination sphere, was synthesized by a sonochemical process to a 3D [Pb(1,4‐BDC)]n (2) coordination polymer with nanoparticle morphology and the same coordination environment was observed upon thermal treatment and dehydration. The color of this compound did not change during the process. This process is irreversible and compound 2 cannot absorb water again. Adsorption and desorption of water in these lead(II) coordination polymers were studied by IR spectroscopy, thermo gravimetric and differential thermal analyses (TG‐DTA), X‐ray powder diffraction (XRD), and scanning electron microscopy (SEM).
