The synthesis and structure of a new class of cyclotriphosphazene transition-metal complexes is described. The complexes have the general structures N3P3X5[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 N3P3F5[(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) ?, b = 10.840 (1) ?, c = 22.122 (3) ?, β = 91.72 (1)°, V = 1548.0 ?3, and Z = 4.
