The First Coordination Polymers withan [O]2[N]P(S)—HgSegment
During the last two decades, design and synthesis of novel coordination polymers are attracting more attention1. In addition, the coordination chemistry of bidentate ligands has been studied for over thirty years2. The bidentate ligands...
Can substitution effect control the metal-ligand polymerization?!
On the base of our previous studies due to the presence of halides in our complexes there is strong probability for obtaining coordination polymers. Crystal engineering well-defined as the understanding of intermolecular interactions in the context...
Constructing magnetic coordination polymers by employing short range bridging ligands in the presence of O, N donor co–ligands and some transition metals under mild and sonochemical conditions
multidentate ligands with metal-short range ligand systems has provided a wealth of magnetic chain compounds. Furthermore, nano–sized particles of coordination polymers are fascinating to explore, since they often exhibit new interesting sized...
Synthesis, structure and DFT study of a chelidamic acid based Cu coordination polymer: On the importance of p–p interactions and hexameric water clusters
One-dimensional coordination polymer, i.e., {(Hampy)[Cu(chel)(H2O)],2H2O}n (1, ampy = 2-amino-6-
methylpyridine, H3chel = chelidamic acid), has been synthesized and characterized by elemental analysis,
IR spectroscopy, solution studies...
Hydrothermal synthesis, X-ray structure and DFT and magnetic studies of a (H2SiW12O40)2− based one-dimensional linear coordination polymer
. Interestingly, L1 and L2 are generated from an in situ transformation of the original ligand, pyridine-2,3-dicarboxylic acid under hydrothermal conditions. Structural analysis showed that this compound is a one-dimensional linear coordination polymer constructed...
The first coordination polymers with an [O]2[N]P(S)-Hg segment: a combined experimental, theoretical and database study
The study of one-dimensional coordination polymers {Hg2Cl4L1}n (1), {HgBr2L1}n (2) and {Hg2Cl4L2}n (3) (L1 = (S)P(OC2H5)2NHC6H4NHP(S)(OC2H5)2 and L2 = (S)P(OC2H5)2NC4H8NP(S)(OC2H5)2) is the first such structural study of Hg(II) coordination polymers...
catena-Poly[[di-miu2-aqua-hexaaquabis(miu3-4-oxidopyridine-2,6-dicarboxylato)trimanganese(II)] trihydrate]: a new one-dimensional coordination polymer based on a trinuclear MnII complex of chelidamic acid
is a one-dimensional coordination polymer, with the twofold symmetric repeat unit containing three metal centres. Two different coordination geometries are observed for the two independent MnII metal centres, viz. a distorted pentagonal bipyramid and a...
Synthesis, single crystal X-ray characterization, and solution studies of Zn(II)-, Cu(II)-, Ag(I) - and Ni(II)-pyridine-2,6-dipicolinate N-oxide complexes with different topologies and coordination modes
In this paper, we have synthesized two new coordination complexes and two coordination polymers at room temperature formulated as}(Htata)2[Cu(pydco)2(tata)]·3H2O{ (1), {(H9a-acr)2·[Ni0.51Zn0.49(pydco)2(H2O)2]·4H2O} (2),] Cu(pydco)(H2O)2[n (3), [Ag...
Hydrogen-bonded 3D network of d10-metal halide coordination polymer containing N--3-pyridinyl- nicotinamide: influence of ligand conformation, halide anions and solvent
In this study, four new d10-metal halide coordination polymers -CPs-, namely [HgCl2 -3-pna-]n -1-, [HgBr2IJ3-pna-]n -2-, [HgI2IJ3-pna-]n CH3OH -3- and [CdI2IJ3-pna-]n -4-, -3-pna = N--3-pyridinyl-nicotinamide- were prepared through the reaction...
Supramolecular assembly of a 2D coordination polymer bearing pyridine-N-oxide-2,5-dicarboxylic acid and copper ion: X-ray crystallography and DFT calculations
As an extension of our interest in pyridine-N-oxide-dicarboxylic acids, we report the design and synthesis of a 2D coordination polymer {[Cu(Hpydco)2]·2H2O}n (1) based on the pyridine-N-oxide-2,5-dicarboxylic acid ligand (H2pydco). 1...
