MAGNETIC STUDIES OF HIGH-SPIN COBALTOUS COMPOUNDS. VII. SOME THIOCYANATE COMPLEXES

摘要: The compound STACo(Ph/sub 3/P)/sub 2/(SCN)/sub 2/! was studied magnetically and spectroscopically. data lead to the following conclusions: (1) is tetrahedral; (2) SCN groups are bound Co via sulfur atoms; (3) position of S-bonded thiocyanate ions in spectrochemical series between Cl/sup -/ Br/sup as previously shown by Schaffer. Several salts STACo(NCS)4!/sup 2-/ anion were A number importart parameters pertaining electronic structure ligand field evaluated effect bonding S atom Hg(II) moving -NCS- ion a stronger series, observed Schaffer, confirmed. 3/PO)/sub 2/(NCS)/sub has been prepared. Comparison spectral magnetic for with similar its chloride bromide analogs shows that this case coordinated through nitrogen atoms. (auth)
