Li·15-crown-52 Ni（mnt）2·2H2O的合成和晶体结构

摘要

The [Li·15-crown-5]2[Ni(mnt)2]·2H2O (1) was obtained by the reaction of H2[Ni(mnt)2], adjusting by LiOH, and crown ether 15-crown-5 in acetone-water solution. Single crystals suitable for X-ray measurement were formed at room temperature. It manifested that 1 crystallized in the monoclinic system, P-1 space group with crystal parameters of a=9. 1082(11) Å, b=11. 1758(13) Å, c=11. 4055(13) Å, α=61. 508(2)°, β=77. 391(2)°,γ=75. 926(2)°, V=982. 6(2), Z=1. In the compound, the [Li·15-crown-5·H2O]+cations and the [ Ni( mnt) 2 ] 2- anions were linked by hydrogen bonds.%在丙酮-水混合溶液中,将LiOH中和的H2[Ni(mnt)2]溶液与冠醚15-crown-5反应得到了化合物[Li·15-crown-5]2[Ni(mnt)2]·2H2O(1)。室温下培养出配合物单晶,通过X射线衍射测定了其晶体结构。结果表明,该配合物属于三斜晶系, P-1空间群,晶胞参数为a=9．1082(11)Å, b=11．1758(13)Å, c=11．4055(13)Å,α=61．508(2)°,β=77．391(2)°,γ=75．926(2)°, V=982．6(2), Z=1。在该配合物中,[Li·15-crown-5·H2O]+阳离子与[Ni(mnt)2]2-阴离子通过氢键相连。
