Four new 1-D coordination polymers have been assembled using bis(4-pyridyl)mercury (py2Hg) as spacer: 1∞[Mn(hfac)2(py2Hg)] 1, 1∞[Zn(CH3COO)2(py2Hg)]∙2H2O 2; 1∞[Ni(dipdtp)2(py2Hg)] 3 (dipdtp = O,O′-diisopropyldithiophosphato), 1∞[Zn(H2O)4(py2Hg)]∙(18C6)(ClO4)2 4 (18C6 = crown ether 1,4,7,10,...
The reaction between the ligand di(4-pyridyl)sulfide (dps) and two salts of divalent first row transition metals (M = Co2+, and Cu2+) resulted in three new compounds with formula: [Co(dps)4(H2O)2](ClO4)2⋅H2O (1), [Cu(dps)2(dmso)2]n(ClO4)2n (2) and [{Cu(dps)2(dmso)2}{Cu(dps)2(dmso)(H2O)}]n(ClO4)4...
Due to the important pharmaceutical activities of benzimidazole derivatives, the differences between 2-(2′-pyridyl)benzimidazole and 2-(4′-pyridyl)benzimidazole were researched by terahertz time-domain spectroscopy and density functional theory systematically. Although the only difference betw...
The changing of the electronic and vibronic states due to the insertion of Zn(II), Cu(II), Ni(II) or Co(II) ions in the meso-tetrakis(4-pyridyl)porphyrin ring center is investigated. The combination of absorption, photoluminescence, Raman and infrared spectroscopies with second-derivative-based ...
In this paper, we report the synthesis, X-Ray structure, FTIR and thermal characterization, and computational investigations of a silver (I) complex, bis (methyl 4-pyridyl ketone) nitrato silver (I) (I),[ Ag(M4PK)2 NO3] (M4PK = methyl 4-pyridyl ketone, C7H7NO). The silver atom in the complex (I)...
An efficient and selective synthesis of Z-(het)arylallylphosphonates is described. The versatile Pd-assisted process also allowed polyarylation sequences leading to star-shaped and binaphthyl derivatives. The methodology could be extended to the preparation of new phosphonomethyl-coumarin, -quin...
Two novel d-d heterometallic cluster-based complexes constructed by N-(Phosphonomethyl)imino-diacetic acid (H4PMIDA) multifunctional ligand, [Cu2Zn2(PMIDA)2(H2O)3]·3H2O(1), [ZnNi14(PMIDA)6(H2O)18]·(NO3)6·15H2O(2), have been synthesized under hydrothermal conditions and characterized by elemen...
Glyphosate [N-(phosphonomethyl)glycine] is a broad spectrum, post-emergent herbicide that is among the most widely used agrochemicals globally. Over the past 30 years, there has been a development of glyphosate-resistant weeds, which pose a significant challenge to growers and crop scientists, r...
The convenient preparation of iminopentitol derivatives, based on a 1,4-dideoxy-1,4-imino-l-arabinitol scaffold carrying β-phosphono(difluoromethyl) or β-phosphonomethyl appendages, as Galf-1P mimics, is reported. The compounds were tested for their ability to inhibit GlfT2, a vital galactofur...
A new complexing adsorbent was prepared by chemical modification of mesoporous silica Kieselgel 60 (dp = 37–63 μm, average pore size 6 nm, specific surface area 425 m2 g−1) with 3-glycidoxypropyltrimethoxysilane and 2-[(phosphonomethyl)amino]acetic acid (PMA), commonly known as glyphosate. The...
