Polyborate Anions Partnered with Large Nonmetal Cations: Triborate(1-), Pentaborate(1-) and Heptaborate(2-) Salts

Tricationic analogues of boroxines and polyborate anions.

Addition of E(2)O (E = Me(3)Si or H) to [(pyridyl)BX(2)][AlX(4)] (X = Cl or Br) and subsequent heating produced the unprecedented trications [(2,6-lutidine)(4)B(5)O(6)](3+) and [(pyridine)(4)B(3)O(3)](3+).

Formulation of Rations with Optimal Cations and Anions for Lactation

Energetic hydrazine-based salts with nitrogen-rich and oxidizing anions.

1,1,1-Trimethylhydrazinium iodide ([(CH(3))(3)N-NH(2)]I, 1) was reacted with a silver salt to form the corresponding nitrate ([(CH(3))(3)N-NH(2)][NO(3)], 2), perchlorate ([(CH(3))(3)N-NH(2)][ClO(4)], 3), azide ([(CH(3))(3)N-NH(2)][N(3)], 4), 5-amino-1H-tetrazolate ([(CH(3))(3)N-NH(2)][H(2)N-CN(4)], 5), and sulfate ([(CH(3))(3)N-NH(2)](2)[SO(4)]·2H(2)O, 6·2H(2)O) salts. The metathesis reaction o...

Immobilization of Phosphomolybdate Anions on the Surface of Magnetite Nanoparticles Modified with Quaternary Phosphonium Cations

A new hybrid nanomaterial was developed by immobilization of phosphomolybdate anions on the surface of modified magnetite nanoparticles with quaternary phosphonium cations. Silica coated magnetic nanoparticles supported phosphonium cations, Ph3P+-SCMNPs, were prepared by covalent attachment of chloropropylsilyl groups on the surface of silica coated magnetite nanoparticles...

Ab initio Molecular Orbital Calculations of Reduced Partition Function Ratios of Polyboric Acids and Polyborate Anions

Molecular orbital calculations at the HF/6-31G(d) level were carried out for polyboric acids and polyborate anions up to a pentamer to estimate their B-to-B isotopic reduced partition function ratios (RPFRs) and examine the additivity of logarithms of RPFRs. Approximate RPFR-values calculated by the use of the additivity agreed with exact RPFR-values within a margin of 1% error. This error was ...
