In situ hydrothermal syntheses, crystal structures and luminescent properties of two novel zinc(II) coordination polymers based on tetrapyridyl ligand

Environmental control in the assembly of metallomacrocycles and one-dimensional polymers with 4,2′:6′:4′′-terpyridine linkers and zinc(ii) nodes

“…6,7,8 Assemblies containing zinc(II) nodes can also be variously directed by the introduction of co-ligands. 8,9 Interconnection of two 4,2':6',4''-tpy metal-binding domains in a ditopic ligand leads to twodimensional networks; the reaction of 1,4-bis(n-octyloxy)-2,5-bis(4,2':6',4''-terpyridin-4'-yl)benzene with ZnCl 2 yields corrugated two-dimensional (4,4) nets which interpenetrate in a 2D → 2D parallel manner. 10 We have previously reported the syntheses of ligands 1 11 and 2 12 4 (2)] n and [Zn 5 (OAc) 10 (2) 4 .…”

Polydentate 4‐Pyridyl‐terpyridine Containing Discrete Cobalt Phosphonate and Polymeric Cobalt Phosphate as Catalysts for Alcohol Oxidation

“…Commercially available starting materials such as Co(OAc) 2 · 4H 2 O (S.D Fine) were used as procured. 4′‐Pyridyl 2,2′:6′,2′′‐terpyridine (pytpy), 2,6‐di iso propylphenyl phosphate (dippH 2 ) and tert ‐butyl phosphonic acid ( t BuPO 3 H 2 ) were synthesized by following reported literature procedures.…”

Single and Double-Stranded 1D-Coordination Polymers with 4′-(4-Alkyloxyphenyl)-3,2′:6′,3″-terpyridines and {Cu2(μ-OAc)4} or {Cu4(μ3-OH)2(μ-OAc)2(μ3-OAc)2(AcO-κO)2} Motifs

“…Multiple-stranded 1D-coordination polymers have also been observed when cadmium(II) acetate or manganese(II) acetate react with some 4 -substituted 4,2 :6 ,4"-tpy ligands, again as a result of the assembly of non-paddle-wheel SBUs [19,21]. The presence of co-ligands often complicates the picture as in the assembly of [{Zn 6 (4-pytpy) 3 (mal) 4 }•5H 2 O] n where 4-pytpy = 4 -(4-pyridyl)-4,2 :6 ,4"-terpyridine and H 2 mal = malic acid (2-hydroxybutanedioic acid) [22]. as exemplified by Zou and coworkers [7].…”

“…The presence of co-ligands often complicates the picture as in the assembly of [{Zn6(4-pytpy)3(mal)4} . 5H2O]n where 4-pytpy = 4'-(4-pyridyl)-4,2':6',4''-terpyridine and H2mal = malic acid (2-hydroxybutanedioic acid) [22]. In a systematic investigation of reactions of zinc(II) acetate with the 4 -(4-alkyloxyphenyl)-4,2 :6 ,4"-tpy ligands shown in Scheme 3, we observed the formation of zigzag 1D-coordination polymers [Zn 2 (µ-OAc) 4 (4 -(4-alkyloxyphenyl)-4,2 :6 ,4"-tpy)] n for short chains (R = Me, Et or n Pr in Scheme 3), but for n-octyloxy, n-nonyloxy and n-decyloxy substituents, discrete [Zn 2 (µ-OAc) 4 (4 -(4-alkyloxyphenyl)-4,2 :6 ,4"-tpy) 2 ] coordination complexes were formed.…”
