Abstract
The reaction between molybdenum trioxide and molten potassium
pyrosulfate was shown by Raman spectroscopy at 430 oC to be a 1:1
reaction. By tempering of the compound, colorless crystals could
be formed. The structure was determined; crystal data: Space group
= P21/c, Z = 4, a = 9.0144(3), b = 12.4540(4), c = 8.8874(3) Å,
beta = 112.194(1)o, wR2 = 0.0897 for 3491 independent reflections.
The compound, K2MoO2(SO4)2, contains (Mo02)2+ core ions in
distorted octahedral coordination, with two short (ca. 1.69 Å)
terminal bonds in cis-configuration (the O-Mo-O angle is
103.1(2)o), and with two long (ca. 2.18 Å) bonds in trans-position
to the short ones, and with two bonds of intermediate (ca. 2.01 Å)
length, all four bridging oxygens belonging to different sulfato
groups. The K+ ions are placed in between strands of Mo06
octahedra, connected along the c-axis by two different kinds of
bridging sulfato groups. Bond distances and angles are compared
with literature values. Empirical correlations between bond
distances and bond orders and bond order sums (approximating
oxidation states) are given for all atoms. IR and Raman spectra
were obtained and tentatively assigned.
