chemical properties yellow fine crystalline powder
uses used to form mixed chloro-aryloxide compounds, such as [nb(oc6h3-2,6-i-pr2)2cl3]2, which form pyridine or phosphine adducts with a distorted six-coordinate geometry.†
uses lewis acid catalyst in organic synthesis.
hazard may evolve fumes of hydrogen chloride. keep dry
safety profile poison by intraperitoneal route. moderately toxic by ingestion. may cause kidney injury. when heated to decomposition it emits very toxic fumes of cl-. see also niobium and chlorides.
purification methods it forms yellow, very deliquescent crystals which decompose in moist air to liberate hcl. it should be kept in a dry box flushed with n2 in the presence of p2o5. wash it with ccl4 and dry it over p2o5. the yellow crystals usually contain a few small, dirty white pellets among the yellow needles. these should be easily picked out. upon grinding in a dry box, however, they turn yellow. nbcl5 has been sublimed and fractionated in an electric furnace.
