The entropies of gaseous UCl 4 calculated from these normal modes and a symmetry number of 12 corresponding to T d symmetry are in good agreement with the experimental counterparts. The ‘best values’ for the two IR-inactive frequencies were obtained by refining a diagonal symmetry force field to the four calculated (density functional) frequencies, the two observed frequencies and the vibrational amplitudes obtained by gas electron diffraction. The calculations yield values for the IR-active modes which are in good agreement with the experimental counterparts. It is tetrahedral with bond distance r e= 251 pm. The molecular structure of UCl 4 has been optimised by density-functional calculations under D 2 d symmetry. What does ZH STRUKT KHIM mean as an abbreviation 1 popular meaning of ZH STRUKT KHIM abbreviation: Vote. Journal of Structural Chemistry is an interdisciplinary publication covering all aspects of structural chemistry, including the theory of molecular structure and chemical bond the use of physical methods to study the electronic and spatial structure of chemical species structural features of liquids, solutions, surfaces, supramolecular systems, nano- and solid materials and the crystal. The gas-phase infrared absorption spectra have been recorded from 25 to 3400 cm –1 at temperatures ranging from 700 to 900 K, and the t 2 stretching and deformation modes have been assigned at ν 3 337.4 and ν 4 71.7 cm –1 respectively. The root-mean-square vibrational amplitudes are l(U–Cl)= 8.9(3) pm and l(Cl ⋯ Cl)= 34.3(10) pm. The data are in good agreement with a model of T d symmetry and a U–Cl bond distance of r a= 250.3(3) pm. The gas electron diffraction pattern of monomeric UCl 4 has been recorded with a nozzle temperature of 900 K.
