Multistimuli Response Micro- and Nanolayers of a Coordination Polymer Based on Cu2 I2 Chains Linked by 2-Aminopyrazine
Small 2017 Sep;13(33):10.1002/smll.201700965.PMID:28692791DOI:10.1002/smll.201700965.
A nonporous laminar coordination polymer of formula [Cu2 I2 (2-Aminopyrazine)]n is prepared by direct reaction between CuI and 2-Aminopyrazine, two industrially available building blocks. The fine tuning of the reaction conditions allows obtaining [Cu2 I2 (2-Aminopyrazine)]n in micrometric and nanometric sizes with same structure and composition. Interestingly, both materials show similar reversible thermo- and pressure-luminescent response as well as reversible electrical response to volatile organic solvents such as acetic acid. X-ray diffraction studies under different conditions, temperatures and pressures, in combination with theoretical calculations allow rationalizing the physical properties of this compound and its changes under physical stimuli. Thus, the emission dramatically increases when lowering the temperature, while an enhancement of the pressure produces a decrease in the emission intensity. These observations emerge as a direct consequence of the high structural flexibility of the Cu2 I2 chains which undergo a contraction in CuCu distances as far as temperature decreases or pressure increases. However, the strong structural changes observed under high pressure lead to an unexpected effect that produces a less effective CuCu orbital overlapping that justifies the decrease in the intensity emission. This work shows the high potential of materials based on Cu2 I2 chains for new applications.
Poly[bis(mu2-2-aminopyrazine-kappa2N1:N4)(mu2-nitrato-kappa2O:O)(nitrato-kappa2O,O')disilver(I)]: an achiral two-dimensional coordination polymer forming chiral crystals
Acta Crystallogr C 2009 Dec;65(Pt 12):m478-80.PMID:19966432DOI:10.1107/S0108270109045806.
The solution reaction of AgNO(3) and 2-Aminopyrazine (apyz) in a 1:1 ratio gives rise to the title compound, [Ag(2)(NO(3))(2)(C(4)H(5)N(3))(2)](n), (I), which possesses a chiral crystal structure. In (I), both of the crystallographically independent Ag(I) cations are coordinated in tetrahedral geometries by two N atoms from two apyz ligands and two O atoms from nitrate anions; however, the Ag(I) centers show two different coordination environments in which one is coordinated by two O atoms from two different symmetry-related nitrate anions and the second is coordinated by two O atoms from a single nitrate anion. The crystal structure consists of one-dimensional Ag(I)-apyz chains, which are further extended by mu(2)-kappa(2)O:O nitrate anions into a two-dimensional (4,4) sheet. N-H...O and C(apyz)-H...O hydrogen bonds connect neighboring sheets to form a three-dimensional supramolecular framework.
Synthesis of some new anils: part 1. Reaction of 2-hydroxy-benzaldehyde and 2-hydroxynaphthaldehyde with 2-aminopyridene and 2-Aminopyrazine
Molecules 2007 Aug 13;12(8):1796-804.PMID:17960088DOI:10.3390/12081796.
New Schiff bases derived from 2-aminopyridene and 2-Aminopyrazine have been synthesized. The UV-Visible spectra of the compounds have been investigated in acetonitrile and toluene. The compounds were in tautomeric equilibrium (enol-imine O- H...N, keto-amine O...H-N forms) in polar and nonpolar solvents. For some derivatives the keto-amine form was observed in both toluene and acetonitrile. 1H-NMR and IR results showed that all Schiff bases studied favor the enol-imine form over the keto form in a weakly polar solvent such as deuterochloroform.
Poly[mu-2-aminopyrazine-kappa2N1:N4-mu-cyanido-copper(I)]: a three-dimensional network from laboratory powder diffraction data
Acta Crystallogr C 2008 Mar;64(Pt 3):m134-6.PMID:18322325DOI:10.1107/S010827010800231X.
In the title compound, [Cu(CN)(C(4)H(5)N(3))](n) or [Cu(mu-CN)(mu-PyzNH(2))](n) (PyzNH(2) is 2-Aminopyrazine), the Cu(I) center is tetrahedrally coordinated by two cyanide and two PyzNH(2) ligands. The Cu(I)-cyano links give rise to [Cu-CN](infinity) chains running along the c axis, which are bridged by bidentate PyzNH(2) ligands. The three-dimensional framework can be described as being formed by two interpenetrated three-dimensional honeycomb-like networks, both made of 26-membered rings of composition [Cu(6)(mu-CN)(2)(mu-PyzNH(2))(4)].
Coordination Polymers Based on Phthalic Acid and Aminopyrazine Ligands: On the Importance of N⁻H···π Interactions
Polymers (Basel) 2018 Feb 13;10(2):182.PMID:30966218DOI:10.3390/polym10020182.
Two new Co(II) and Cu(II) coordination polymers, {Co(HL₁)₂(μ-L₂)(H₂O)₂}n (1) and {[Cu(HL₁)₂(μ-L₂)H₂O]·H₂O}n (2) (H₂L₁ = Phthalic acid and L₂ = 2-Aminopyrazine), have been synthesized by slow evaporation of solvent and characterized by IR spectroscopic, elemental, single-crystal X-ray diffraction and thermal analysis. X-ray results indicate that in both the polymers, phthalate acts as a monodentate ligand and the aminopyrazine ligand is responsible for the formation of the infinite one-dimensional chain structure. The solid-state structures are stabilized through hydrogen bonds and N‒H···π interactions by generating two-dimensional layered structures. Finally, the non-covalent interactions have been studied energetically and using Bader's theory of atoms in molecules by means of Density Functional Theory (DFT) calculations. The influence of the metal coordination on the strength of the interaction has been studied using molecular electrostatic potential surface calculations.
