Our X-ray powder diffraction data determine that UTeO₄ has an orthorhombic unit cell with parameters a=510.115±0.003 Å ,b=510.706±0.002 Å ,c=57.833±0.002 Å ,and v=5848±0.40 ( Å )^3, i.e., the cell volume twice as large as that of UTeO₅ . IR spectral studies show that UTeO₄ and UTeO₅ have almost an identical molecular symmetry. In UTeO₄, the effective environment of U and Te remains nearly the same as in UTeO₅ and the UO₂ group is noncentrosymmetric and nonlinear with little or no interaction with equatorial oxygen. Frequencies of the characteristic stretching bands of UTeO₄ are(Cm^-1):^{_vas(O=U=O)=945},V^S(O=U=o)= 880,v^{s (}Te–O) eq=818,v^as(Te–o)eq=749,v^as(Te – O)ax=649,v^s(Te – O)ax=561
