Abstract: The reactions of triamminotricarbonylchromium (I) with 1,3-benzodioxane (L1), 2-methyl-1,3-benzodioxane (L2), and 2-phenyl-1,3-benzodioxane (L3) afford new complexes: (η6-C8H8O2)Cr(CO)3 (II), exo- and endo-[2-Me-(η6-C8H7O2)]Cr(CO)3 (III, IV), exo- and endo-[2-Ph-(η6-C8H7O2)]Cr(CO)3 (V, VI), [2-(η6-Ph)-C8H7O2]Cr(CO)3 (VII), and endo-[2-(η6-Ph)]Cr(CO)3-[η6-C8H7O2]Cr(CO)3 (VIII). The structures, compositions, and purity of the synthesized products are proved by UV, IR, and 1H NMR spectroscopy, HPLC, and mass spectrometry. The molecular structures of complexes IV–VI are determined by XRD (CIF files CCDC nos. 2263301 (IV), 2295552 (V), and 2237106 (VI)). A possibility of coordination of the tricarbonylchromium group at different sides of the phenylene ring of ligands L2 and L3 and on the phenyl substituent of ligand L3 is shown.
