Niobium oxychloride is theinorganic compound with the formula NbOCl3. It is a white, crystalline, diamagneticsolid. It is often found as an impurity in samples ofniobium pentachloride, a commonreagent in niobium chemistry.
In the solid state thecoordination sphere for niobium is a distortedoctahedron. The Nb–O bonds and Nb–Cl bonds are unequal. This structure can be described as planar Nb2Cl6 core connected by O–Nb–O bridges. In this way, the compound is best described as a polymer, consisting of a double stranded chain.[1][2]
