“…3. In comparison with previous research works reported on similar compounds containing [BiCl 5 ] [16,17], the Raman spectrum of [C 6 H 18 N 2 O] 2 Bi 2 Cl 10 Á2H 2 O is found to be similar to that of [NH 3 (CH 2 ) 5 NH 3 ]BiCl 5 [18] registered at 303 K. The highintensity band detected at 266 cm -1 is assigned to the terminal Bi-Cl bonds, and the weak band observed at 220 cm -1 is assigned to the bridging Bi-Cl stretching vibrations. The bands corresponding to the Cl-Bi-Cl deformation mode appear at 167 cm -1 .…”

The synthesis and the structures of two new compounds with the general formula [C 6 H 18 N 2 O] 2 Bi 2 X 10-2H 2 O (X = Br, Cl) are reported. They crystallize in the triclinic system and are isostructural. Crystal structures were solved and refined to R = 0.064, 0.048 and R w = 0.15, 0.13 using 3392, 3679 independent reflections for the Cl and Br derivatives, respectively. The atomic arrangement can be described by inorganic chains along the [100] direction. These chains are themselves interconnected by means of N-HÁÁÁX (X = Cl, Br) originating from the [C 6 H 18 N 2 O] 2? entities, to form three-dimensional network. The organic part consists of one organic cation which orients its two amine groups to the neighboring anions. The inorganic entity is made up of [Bi 2 X 10 ] 4-dimers composed of two equivalent irregular octahedra sharing one edge. The oxygen atoms of the water molecules (OW) act as donor (O-HÁÁÁX) and acceptor (N-HÁÁÁO) of hydrogen bonds. The nature of the distortion of the inorganic polyhedra can be attributed to the stereoactivity of the Bi(III) lone electron pair. Raman and infrared spectra at room temperature were recorded in the 500-100 and 4000-400 cm -1 frequency regions, respectively. This study confirms the presence of the organic cation [C 6 H 18 O] 2? and the bioctahedron [Bi 2 X 10 ] 4-. The calorimetric study shows that the title compound is stable until 384 K.

Ab initio and density functional theory computations have been carried out to calculate the structures and vibrational spectra of halobismuthates and haloantimonates of formulas MX6(3-), M2X10(4-), and M2X9(3-) for M = Bi or Sb and X = I, Br, or Cl. The results have been compared to experimental crystal structures and the infrared and Raman spectra of these species as well as the (MX5(2-))n and (MX4(1-))n anions. Even though the calculations neglect the effect of which cation is present, they do a good job in verifying the observed trends in bond distances and bond stretching vibrational frequencies. External bonds across from bridging bonds are the shortest and have the highest stretching frequencies for all of the ions investigated. This supports the previously postulated "trans effect". Since the calculations were carried out for individual noninteracting anions, the computed results can be expected to best represent the idealized species unperturbed by the effect of the cations present. The trans effect results in shortening of the M-X bonds by 0.08-0.13 Å. It also leads to frequency increases of about 20% for the M-X stretching vibrations.
