Synthesis and Crystal Structure of [Li·15- crown- 5]_2[Ni(mnt)_2]·2H_2O

在丙酮-水混合溶液中,将Li OH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),b=11.1758(13),c=11.4055(13),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。

The [Li·15- crown- 5]2[Ni（mnt）2]·2H2O（1） was obtained by the reaction of H2[Ni（mnt）2],adjusting by Li OH,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） A°,b = 11. 1758（13） A°,c = 11. 4055（13）A°,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.
