Crystal data for the complexes of triphenylphosphine oxide (TPPO) and benzyldiphenylphosphine oxide (BDPPO) with cobalt (II) thiocyanate

Crystal data for TPPO and BDPPO complexes with cobalt (II) thiocyanate, space group R32 (a = 17.50±0.06 Å, b = 30.99±0.08 Å) and Pbcn (a = 10.10±0.01 Å; b = 20.22±0.03 Å; c= 18.94±0.01 Å), respectively, suggest C₂ as the only compatible symmetry for both complexes. Optical, morphological and X-ray powder data are given.
