Molecular metallocycles, acyclic metallodimers and 2D coordination polymers containing the twisted ligand bis(pyrimidin-2-ylthio)methane.
The versatile coordination chemistry of bis(pyrimidin-2-ylthio)methane (bptm) allows the synthesis of a series of different metal complexes with diverse structures. We describe here the synthesis and structural characterization of three kinds of compounds: four cyclic dimers, [Co(2)Cl(4)(bptm)(2)] (1), [Zn(2)I(4)(bptm)(2)] (2), [Cd(2)I(4)(bptm)(2)] (3), [Cu(2)(NO(3))(4)(bptm)(2)] (4); two acycl...
متن کاملAzo-Containing Polymers with Degradation On-Demand Feature
Molecules comprising aliphatic azo moieties are widely used as radical polymerization initiators, but only few studies have explored their usefulness as stimuliresponsive motifs in macromolecular constructs. The controlled degradation of azo-containing polymers has indeed remained largely unexplored. Here we present the syntheses of linear azocontaining polyamides and polyurethanes and report o...
متن کاملSynthesis and photoreactions of aromatic diols containing bis (azo) and bis (o-nitrobenzyl) chromophores
Aromatic diols containing bis (azo) and bis (o-nitrobenzyl) chromophores viz., (4hydroxyphenylazo)-2,2/-dinitrodiphenylmethane, 4-hydroxy-3-methylphenylazo-4/-hydroxyphenylazo-2,2/-dinitrodiphenyl methane and bis (4-hydroxy-3-methylphenylazo)-2-dinitrodiphenyl methane were synthesized from 4,4-diamino-2,2/-dinitrodiphenylmethane and phenol/0-cresol. As a result of photolysis, the azo group of t...
متن کاملCoordination polymers containing ferrocene backbone. Synthesis, structure and electrochemistry.
The reaction of 1,1'-ferrocenedicarboxylic acid (LH(2)) with bis(triphenyltin) oxide afforded a molecular heterobimetallic compound [(Ph(3)Sn)(2)L]. In the latter the two carboxylate units of [L](2-) are involved in an anisobidentate chelating coordination mode to two triphenyl tin units. The reaction of LH(2) with trimethyltin hydroxide or bis(tri-n-butyltin) oxide afforded 2D-coordination pol...
متن کاملSynthesis, Crystal Structures and Properties of New Barium Thiocyanato Coordination Polymers with trans-1,2-Bis(4-pyridyl)ethylene as Ligand
Reactions of barium thiocyanate with trans-1,2-bis(4-pyridyl)ethylene (bpe) in acetonitrile/water using different molar ratios always lead to the formation of a new barium coordination polymer of composition {[[Ba(NCS)(H2O)5]2](bpe)}(NCS)2(bpe)3(H2O)2 (1). During the preparation of single crystals of compound 1, three additional new compounds were obtained (2 – 4), of which one crystallizes in ...
