元素磷和砷形成四面体P4和As 4分子，其中前者是商品化学品，后者不稳定。以前，关于中间成分的分子的信息仅限于涉及磷和砷的热气相混合物的光谱研究。AsP3分子已通过化学合成，并以固体形式分离为纯物质，熔点为71° C至73°C。描述了AsP3的物理性质和光谱表征数据，并确定其结构为配位络合物中的配体。可溶于有机溶剂，AsP3代表了任何合成的一个有吸引力的起点，其中目标分子或材料含有精确的1：3的砷与磷的比例。
The elements phosphorus and arsenic form tetrahedral P4 and As4 molecules, of which the former is a commodity chemical and the latter unstable. Previously, information on molecules of intermediate composition was limited to a spectroscopic study involving hot gas-phase mixtures of phosphorus and arsenic. The AsP3 molecule has yielded to chemical synthesis and was isolated in solid form as a pure substance with a melting point from 71° to 73°C. Physical properties and spectroscopic characterization data for AsP3 are described, and its structure was determined as a ligand in a coordination complex. Soluble in organic solvents, AsP3 represents an attractive starting point for any synthesis in which the target molecule or material contains an exact 1:3 ratio of arsenic to phosphorus.
