Description / Table of Contents:
Pentacarbonyl Chromium Complexes of SF5-substituted IsocyanidesThe syntheses of [(F5S—N = CCF3—NC)Cr(CO)5], [(F5S—N = CC3F7—CN)Cr(CO)5] and [F5S—N = C(NCCr(CO)5)2] are reported. The structure of the last-named compound, triclinic, P1, a = 640.70(10), b = 1197.5(2), c = 1423.5(2) pm, α = 92.560(10), β = 63.410(10), γ = 99.710(10)º, Z = 2, R1 = 0.0512, wR2 = 0.1533, has been elucidated by X-ray diffraction. The analogous tellurium compound is thermally unstable and can not be obtained in substance.
Notes:
Es wird über die Synthesen von [(F5S—N = CCF3—NC)Cr(CO)5], [(F5S—N = CC3F7—CN)Cr(CO)5] und [F5S—N = C(NCCr(CO)5)2] berichtet. Die Struktur des letztgenannten Komplexes, triklin, P1, a = 640.70(10), b = 1197.5(2), c = 1423.5(2) pm, α = 92.560(10), β = 96.410(10), γ = 99.710(10)º, Z = 2, R1 = 0.512, wR2 = 0.1533, konnte durch eine Einkristallröntgenstrukturanalyse bestimmt werden. Die homologe Verbindung [F5Te—N = C(NCCr(CO)5)2] ist thermisch instabil und kann nicht in Substanz erhalten werden.
