obtained for arsonoacetic acid, As(CH2COOH)O3H2, and its barium and sodium salts. The X-ray crystal structure of the free acid is isomorphous with phosphonoacetic acid. Reduction gave the As(I) compound arsenoacetic acid, (AsCH2COOH)n which was shown by ESI-MS to contain cyclic species based on As–As bonds, with n mainly 3–6. The X-ray crystal structure of the hexamer was determined as the pyridine solvate
已获得有关砷乙酸,As(CH 2 COOH)O 3 H 2及其钡和钠盐的详细光谱数据。游离酸的X射线晶体结构与膦酰基乙酸同构。还原得到的As(I)化合物砷乙酸(AsCH 2 COOH)n由ESI-MS显示包含基于As-As键的环状物质,n主要为3-6。六聚体的X射线晶体结构确定为吡啶溶剂化物,并显示在褶皱的椅子构象中具有六环As 6环,在赤道位置带有–CH 2 COOH基团,每个H键键合到吡啶分子中的吡啶分子上。格子。
