The tungsten/vanadium ratios for the known ternary compounds in the V2O5WO3VO2 chemical system are characterized. The compounds V2.5W.5O7 and V2WO7.5 are the n = m = 3 and n = m = 4 members of a sreies of M-niobia like crystallographic shear structures. We have found the n = m = 5 member of the series at the composition V3.2W1.8O13, and report its crystallographic unit cell, powder x-ray diffraction pattern and range of temperature stability.
