Ara, Rifat published the artcileChemistry, urease inhibition, and phytotoxic studies of binuclear vanadium(IV) complexes, Formula: C7H7IN2O, the publication is Chemistry & Biodiversity (2007), 4(1), 58-71, database is CAplus and MEDLINE.

Vanadium plays an important role in biol. systems and exhibits a variety of bioactivities. In an effort to uncover the chem. and biochem. of vanadium with nitrogen- and oxygen-containing ligands, we report herein the synthesis and spectroscopic characterization of vanadium(IV) complexes with hydrazide ligands. Substituents on these ligands exhibit systematic variations of electronic and steric factors. Elemental and spectral data indicate the presence of a dimeric unit with two vanadium(IV) ions coordinated with two hydrazide ligands along with two H₂O mols. The stability studies of these complexes over time in coordinating solvent, DMSO, indicates binding of the solvent mols. to give [V₂O₂L₂(H₂O)₂(DMSO)₂]²⁺ (L = hydrazide ligand) and then conversion of it to a monomeric intermediate species, [VOL(DMSO)₃]¹⁺. Hydrazide ligands are inactive against urease, whereas vanadium(IV) complexes of these ligands show significant inhibitory potential against this enzyme and are found to be non-competitive inhibitors. These complexes also show low phytotoxicity indicating their usefulness for soil ureases. Structure-activity relationship studies indicate that the steric and/or electronic effects that may change the geometry of the complexes play an important role in their inhibitory potential and phytotoxicity.

Ashiq, Uzma published the artcileSynthesis, spectroscopy, and biological properties of vanadium(IV)-hydrazide complexes, COA of Formula: C7H7IN2O, the publication is Chemistry & Biodiversity (2008), 5(1), 82-92, database is CAplus and MEDLINE.

The synthesis, spectroscopic, enzyme-inhibition, and free-radical-scavenging properties of vanadium(IV) substituted benzohydrazide complexes, 1–10, were studied. These complexes exhibit a dimeric structure with hydrazide ligands coordinated in a bidentate fashion. All complexes are stable in the solid state, but exhibit varying degrees of stability in solution In coordinating solvent such as DMSO, stepwise binding of two solvent mols. at the 6th positions trans to the V=O bond of the dimeric unit is observed The dimeric compounds are converted to monomeric species in which both solvent mols. and the hydrazide ligands are coordinated to the V^IV center. The free substituted benzohydrazides 11–20 were inactive against α-glucosidase, but their V^IV complexes showed varying degrees of inhibition, depending on the type of ligand. The DPPH-radical-scavenging activities of 1–20 were determined, which indicated that steric and/or electronic effects responsible for changes in geometry play important roles in terms of antioxidant potential.

Zhai, Tianran published the artcileFerrocene metallopolymers of intrinsic microporosity (MPIMs), COA of Formula: C6H13I, the publication is Chemical Communications (Cambridge, United Kingdom) (2022), 58(2), 238-241, database is CAplus and MEDLINE.

We show here that non-network metallopolymers can possess intrinsic microporosity stemming from contortion introduced by metallocene building blocks. Metallopolymers constructed from ferrocenyl building blocks linked by phenyldiacetylene bridges are synthesized and possess BET surface areas up to 400 m² g^-1. As solubility imparted by pendant groups reduces porosity, copolymerization is used to simultaneously improve both accessible surface area and solubility Spectroscopic anal. provides evidence that mixed valency between neighboring ferrocenyl units is supported in these polymers.

Whitaker, R. D. published the artcileIodine monochloride and iodine trichloride systems involving pyridine and quinoline, Application of Pyridine Iodochloride complex, the publication is Journal of Inorganic and Nuclear Chemistry (1962), 285-9, database is CAplus.

Spectrophotometric studies indicate that only addition compounds with 1:1 stoichiometries are present in significant concentrations in CCl⁴ solutions of ICl or ICl, with heterocyclic amines. However, thermal studies reveal that in the solid state, in addition to the expected 1:1 type compounds, the system ICl₄-pyridine forms C₅H₆N.2ICl₃ (m.p. 140°) and ICl₃.2C₅H₅N (m.p. 69° incongruent) and the system ICl₂-quinoline forms ICl₂.2C₉H₇N (m.p. 81°). The system ICl-quinoline forms only the 1:1 type compound, and a reinvestigation of part of the system ICl-pyridine confirmed the absence of a compound with a mole ratio of 1: 2 of ICl to pyridine.

In order to avoid the fading of the spots, some aromatic amines were used as a second spray on the chromatograms previously treated with the ceric sulfate-arsenious acid reagent. Most of these drugs gave 1 spot on paper and a silica gel layer. Iodochlor-hydroxyquin gave 2 spots on silica gel, and 3 spots on plates covered with polyamide.
