摘要：

The crystal structures of cis-(n-Bu4N)(2)[ReCl4(NCS)(2)] (triclinic, space group P (1) over bar, a = 11.245(1), b = 20.174(3), c = 21.320(8) Angstrom, alpha = 109.06(2), beta = 96.46(2), gamma = 98.22(5)degrees, Z = 4) and cis-(Ph4P)(2)[ReCl4(NCSe)(2)]. 2CH(2)Cl(2) (triclinic, space group P (1) over bar, a = 10.341(2), b = 13.436(3), c = 19.616(4) Angstrom, alpha = 92.70(2), beta = 92.02(2), gamma = 89.99(1)degrees, Z = 2) have been determined by single crystal X-ray diffraction analysis. Both ambidentate ligands NCS and NCSe are bonded via the N atom. Using 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 based on a modified valence force field. The Valence force constants f(d)(ReN) are 1.78(NCS) and 1.79(NCSe) mdyn/Angstrom.
