The crystal structure of di-n-butylarsinic acid
TLDR
The crystal structure of di-n-butylarsinic acid has been determined from 1257 independent photographically recorded intensities as discussed by the authors, where the acid molecules are present as non-planar, H-bonded dimers across the centers of symmetry in the cell.About:

Oxidation of (AsPh2)2E(E=O or S); supramolecular hydrogen-bonded self-assembly of an unusual tetranuclear adduct and crystal structure of [AsPh2(O)OH · AsPh2(S)OH]2

TL;DR: In this article, it has been shown that in the case where E = O or S, the dioxidation produces less stable compounds and recrystallisation of the products from oxidation of (AsPh 2 ) 2 O with sulfur and AsPh 2 2 S with tert-butyl hydroperoxide leads to a mixed arsinic acid-monothioarsonic acid mixture.

Preparation of pseudo-arsonolipids: 2-acyloxypropane-1,3-bis(arsonic acids). The crystal structure of 2-hydroxypropane-1,3-bis(arsonic acid).
TL;DR: Epihalohydrins react with alkaline arsenite to give in very good yields 2-hydroxypropane-1,3-bis(arsonic acid) (7), a key compound for the synthesis of pseudo-arsonolipids and more complex arsinolipIDS.

The crystal structure of n-propylarsonic acid
TL;DR: The crystal structure of n-propylarsonic acid has been determined by single crystal X-ray diffractometer methods as mentioned in this paper, and the crystal is orthorhombic, Pccn, b = 11.024(4), c = 7.692(3) at 22°, 8 molecules/unit cell.

Di(n-octyl)arsenic acid (DOAA) as a reagent for liquid-liquid extraction—I: Extraction of mineral acids
A.M. Olivares,Kurt J. Irgolic +1 more
TL;DR: In this paper, aqueous solutions of dioctylarsinic acid (DOAA), (n -C 8 H 17 ) 2 AsOOH, in chloroform have been equilibrated with solutions of perchloric, hydrochloric and hydriodic acids, and the loading curves for the other mineral acids are similar to the curve for HClO 4 with well defined plateaus at equimolar ratios.

The enthalpies of fusion and transition and X-ray powder patterns of 20 DI-n-alkylarsinic acids
TL;DR: The enthalpies and temperatures of fusion and transition for twenty arsinic acids, R 2 As(O)OH, have been measured by DTA, where R = n -alkyl, CH 3 through n -C 20 H 41 inclusive as mentioned in this paper.
