本文中,我们报道了公知的(S)-L-ala-Ni-BPB配合物(1)的第一个X射线晶体结构,并将其与两种新的氟化(S)-L-ala-Ni-BPB配合物(8和12)获得的X射线晶体结构进行比较,所述氟化(S)-L-ala-Ni-BPB配合物(8和12)在BPB配体的脯氨酸环上含有S-或R-氟原子。通过合成两个新的氟化BPB配体(7和11),能够制备配合物8和12。在这项工作中,我们希望观察结构的影响,一个单一的氟原子的引入上已知的配合物1。由此产生的,我们强调了一种新的氟-镍相互作用,可以提供额外的稳定配合物8。
Herein we report the first X-ray crystal structure of the well-known (S)-L-ala-Ni-BPB complex (1) and compare this with the X-ray crystal structures obtained for two novel fluorinated (S)-L-ala-Ni-BPB complexes (8 and 12) that contain either an S- or R-fluorine atom on the proline ring of the BPB ligand. The preparation of complexes 8 and 12 has been enabled by the synthesis of two new fluorinated BPB ligands (7 and 11). In this work we looked to observe structural effects that the introduction of a single fluorine atom has on the known complex 1. Arising from this, we highlight a novel fluorine – nickel interaction that may provide additional stabilisation to complex 8.
