Syntheses and crystal structure of first octahedral d-metal complexes containing three and four isocyanato ligands, mer-[Mo(NCO)3py3] · 2py and trans-(py2H)[Mo(NCO)4py2]
摘要:
By refluxing of a mixture of (NH4)(2)[MoCl5(H2O)] and KOCN in pyridine, the neutral mer-[Mo(NCO)(3)py(3)] and anionic trans[Mo(NCO)(4)py(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)(3)py(3)] center dot 2py (1) and (py(2)H)[Mo(NCO)(4)py(2)] (2) have been prepared and crystal structures of both were determined by X-ray crystallography.
