Double and Triple Interpenetrations of the Three-Dimensional Frameworks [Cd(mea)(daptn){Ni(CN)4}] and [Cd(mea)(dahxn){Ni(CN)4}].H2O (mea = 2-Aminoethanol, daptn = 1,5-Diaminopentane, dahxn = 1,6-Diaminohexane)

The two-dimensional coordination polymer poly[[bis(3-methylpyridine)cadmium(II)]-tetra-μ-cyano-nickel(II)]

“…Similar corrugated polymeric layers are also reported in some related compounds (Erdo È nmez et al, 1998). The CÐN and NiÐC bond distances of the square-planar Ni coordination environment are comparable with those in related Ni(CN) 4 complexes (Karadag AE et al, 2004;Yuge & Iwamoto, 1995;Yuge et al, 1996;Woodward et al, 2001).…”

Constructing Terbium Co-ordination Polymers of 4,4′-Bipyridine-N,N′-dioxide by Means of Diffusion Solvent Mixtures

“…Threefold interpenetrating co-ordination networks based on four-connected centres are scarce to date. Previous examples of threefold interpenetrating diamondoid nets, including [{Cu(diazapyrene) 2 ]PF 6 } I , [15] {[Cu(dmtpn) 2 ](X)(dmtpn)-(THF)} I (X BF 4 , ClO 4 ; dmtpn 2,5-dimethylterephthalonitrile), [16] [Cu(CN)(4-cyanopyridine)] I , [17] [Ag 2 {OOC(CH 2 )-COO}] I , [18] and {[Cd(mea)(dahxn){Ni(CN) 4 }] ¥ H 2 O} I [19] are all constructed from d-metal junctions. To our knowledge, no example of threefold interpenetrating networks has been reported for lanthanide co-ordination polymers, [20] although a few examples of twofold interpenetrating structures have been reported.…”

Coordination Polymer Based on a Triangular Carboxylate Core {Fe(μ3-O)(μ-O2CR)6} and an Aliphatic Diamine

“…Subsequently, the pre-organized complex was treated with 1,6-diaminohexane to obtain the desired polymer complex. The mechanism of this reaction, involving either substitution of the bidentate ligand or the formation of a heteroleptic complex, remained uncertain due to the possibility of both pathways [29,30,53,54]. We previously proposed a similar synthetic protocol to obtain 3d-4f heterometallic carboxylate complexes with N-heterocyclic carbenes [55] and phosphine ligands [56].…”
