Synthesis, structure and property of serial p-carboxylphenoxyacetate-lanthanide coordination polymers

Synthesis, structure and properties of 2D lanthanide coordination polymers based on N-heterocyclic arylpolycarboxylate ligands.

The reaction of 3-(2,4-dicarboxyphenyl)-2,6-pyridinedicarboxylic acid (H4dppd) with rare earth nitrates under hydrothermal conditions generated a series of new two-dimensional (2D) coordination polymers, namely {[La(Hdppd)(H2O)2·(H2O)2]n (1), [Ln2(Hdppd)2(H2O)4·(H2O)3]n [Ln = Sm (2), Eu (3)] and [Ln(Hdppd)(H2O)3·H2O]n [Ln = Gd (4), Tb (5), Dy (6), Ho (7), Er (8)] [Hdppd = 3-(2,4-dicarboxyphenyl...

Ionothermal synthesis , crystal structure , topology and catalytic property of heterometallic coordination polymers

Synthesis and coordination behaviors of P-stereogenic polymers.

Optically active polymers containing P-stereogenic bisphosphine and 1,2,3-triazole units in the main chain were obtained by copper-catalyzed Huisgen cycloaddition. The repeating unit of the polymer adopted bidentate as well as tetradentate coordination, leading to the change in the conformations of the polymer via complexation with transition metals.

Syntheses, structures, and photoluminescence of 1-D lanthanide coordination polymers.

Five new lanthanide 1-D coordination polymers are reported which are formed from flexible salen type Schiff-base ligands H(2)L and H(2)L' (H(2)L = N,N(1)-ethylene bis(salicylideneimine); H(2)L' = N,N(1)-bis(3-methoxysalicylidene)ethylene-1,2-diamine). The polymeric structures are formed by bridging neutral H(2)L units in the case of {[Ln(2)L(2)(CF(3)SO(3))(H(2)L)(4)(MeOH)] x CF(3)SO(3)}(n) (Ln ...

Microporous chiral metal coordination polymers: hydrothermal synthesis, channel engineering and stability of lanthanide tartrates.

L-Tartrate ions can endure hydrothermal conditions up to 160 degrees C to form the robust, enantiopure open-framework coordination polymers [Ln2(L-TAR)3(H2O)2]3H2O, 1; the addition of succinate results in formation of the related [Ln2(L-TAR)2(SUC)(H2O)2]5.5H2O, with larger channels than , whereas racemic D/L-tartrate gives the more condensed [Ln2(D/L-TAR)3(H2O)2], . TAR = [C4H4O6]2-.
