【 摘 要 】

The syntheses and single-crystal structures of Mo(CO)₃(phen)(dipy) (1), Mo(CO)₃(biquin)(dipy) (2) and Mo(CO)₃(dpme)(dipy) (3), (phen = 1,10-phenanthroline, C₁₂H₈N₂; dipy = 2,2′-dipyridylamine, C₁₀H₉N₃; biquin = 2,2′-biquinoline, C₁₈H₁₂N₂; dpme = 2,2′-dipyridylmethane, C₁₁H₁₀N₂) are described. In each case, distorted fac-MoC₃N₃ octahedral coordination geometries arise for the metal atoms. Short intramolecular N–H⋯C interactions from the dipy N–H group to a carbonyl carbon atom occur in each structure. Crystal data: 1 (C₂₅H₁₇MoN₅O₃), M_r = 531.38, monoclinic, P2₁/n (No. 14), Z = 4, a = 11.0965 (5) Å, b = 13.0586 (6) Å, c = 16.6138 (8) Å, β = 108.324 (1)°, V = 2285.31 (18) ų, R(F) = 0.035, wR(F²) = 0.070. 2 (C₃₁H₂₁MoN₅O₃), M_r = 607.47, monoclinic, P2₁/n (No. 14), Z = 4, a = 11.4788 (6) Å, b = 19.073 (1) Å, c = 11.9881 (6) Å, β = 95.179 (1)°, V = 2613.9 (2) ų, R(F) = 0.030, wR(F²) = 0.076. 3 (C₂₄H₁₉MoN₅O₃), M_r = 521.38, monoclinic, P2₁/n (No. 14), Z = 4, a = 8.4222 (3) Å, b = 21.5966 (9) Å, c = 12.5011 (5) Å, β = 94.065 (1)°, V = 2268.12 (15) ų, R(F) = 0.025, wR(F²) = 0.065.
