Abstract

The synthesis and structure of a new class of cyclotriphosphazene transition-metal complexes is described. The complexes have the general structures N₃P₃X₆[RCr(CO)₃], where the X and R substituents are fluoro and phenyl, trifluoroethoxy and phenyl, chloro and phenoxy, trifluoroethoxy and phenoxy, and n-propylamino and phenoxy, respectively, N₃P3R₅[RCr(CO)3], where the R substituents are phenoxy, 4-methylphenoxy, 4-methoxyphenoxy, phenyl, 2-phenoxyethoxy, and anilino, and N₃P₃[RCr(CO)₃]₆, where the R substituents are phenoxy and 2-phenoxyethoxy. Species N₃P₃[RCr(CO)₃]₆ represent unique examples of cyclotriphosphazenes that possess one transition metal on each side-group structure. The molecular structure of N₃P₃F₆[(C₆H₅)Cr(CO)₃] has been determined by X-ray diffraction. The crystals are monoclinic with space group P2₁/c, with a = 6.458 (1) Å, b = 10.840 (1) Å, c = 22.122 (3) Å, β = 91.72 (1)°, V = 1548.0 Å³, and Z = 4.
