The compounds fac-(魏³-PDP)Mo(CO)₃ {1; PDP = 2-[[2-(1-(pyridin-2-ylmethyl)pyrrolidin-2-yl)pyrrolidin-1-yl]methyl]pyridine}, [(cis-尾-PDP)Mo(NO)(CO)]PF₆ ([cis-尾-3]PF₆), [(cis-伪-PDP)Mo(NO)(CO)]PF₆ ([cis-伪-3]PF₆), [(cis-伪-PDP)Mo(NO)Br]PF₆ ([4]PF₆), [(trans-PDP)Cu](BF₄)₂路CH₃CN ([5](BF₄)₂路CH₃CN), and [(trans-PDP)Cu](OSO₂CF₃)₂ ([5](OSO₂CF₃)₂) have been synthesized and structurally characterized by single-crystal X-ray diffraction. These are the first reported complexes of PDP on metal centers other than iron(II). The observed configurations indicate a broader range of accessible PDP topologies than has been reported. The {(cis-伪-PDP)Mo(NO)}⁺ fragment is found to be less 蟺-basic than the dearomatizing {Tp(MeIm)Mo(NO)} fragment [Tp = hydridotris(1-pyrazolyl)borato; MeIm = 1-methylimidazole].
