Syntheses and crystal structure of first octahedral d-metal complexes containing three and four isocyanato ligands,mer-[Mo(NCO)_3py_3] centre dot 2py and trans-(py_2H)[Mo(NCO)_4py_2]

摘要

By refluxing of a mixture of (NH_4)_2[MoCl_5(H_2O)] and KOCN in pyridine,the neutral mer-[Mo(NCO)_3py_3] and anionic trans-[Mo(NCO)_4py_2]~- species originated simultaneously at reflux temperature.After a separation of the water-unsoluble neutral and water-soluble ionic species,the single crystals of compounds [Mo(NCO)_3py_3] centre dot 2py (1) and (py_2H)[Mo(NCO)_4py_2] (2) have been prepared and crystal structures of both were determined by X-ray crystallography.
