The crystal structures of cis-(n-Bu4N)2[ReCl4(NCSe)(SeCN)] (monoclinic, space group P21/n a = 10.794(3), b = 11.687(3), c = 35.716(4) Å, β = 96.97(1)°, Z = 4) and trans- (CH2Py2)[ReCl4(NCSe)(SeCN)] (monoclinic, space group P21/c, a = 8.348(2), b = 7.518(1), c - 31.295(7) Å, ß = 97.12(2)°, Z = 4) have been determined by single crystal X-ray diffraction analysis. Based on the molecular parameters of the X-ray determinations the low temperature (10 K) IR and Raman spectra of the (n-Bu4N) salts have been assigned by normal coordinate analysis. The valence force constants are fd(ReN) = 1.68 and fd(ReSe) =1.15 mdyn/Å.

Keywords : cis-Tetrachloroselenocyanato(N)-selenocyanato(Se)-rhenate(IV); trans-Tetrachloroselenocyanato(N)-selenocyanato(Se)-rhenate(IV); Crystal Structure; Vibrational Spectra; Normal Coordinate Analysis
