The necessary conditions for preparation of TaBr4 and TaI4 by reduction of the pentahalides with tantalum or aluminum metal in a sealed tube under a controlled temperature gradient have been demonstrated. An unusual, but more fruitful synthesis of TaI4 was devised from the reduction of TaI5 with pyridine. X-Ray powder patterns of diamagnetic, isomorphous TaCl4 and TaBr4 were indexed on an orthorhombic unit cell of dimensions a = 8.10, b = 8.92, c = 6.80 ?. and a = 8.58, b = 9.30, c = 7.21 ?., respectively. The compounds TaCl4(C5H5N)2 and TaBr4(C5H5N)2 were prepared by the reaction of pyridine with the respective tetrahalides at room temperature. Unusually low magnetic moments of 0.69 and 0.43 B.M. were found for the chloride- and bromide-pyridine adducts, respectively.
