摘要: 分别以2-[(4-二甲氨基苯基偶氮]-1-甲基-吡啶阳离子、2-[(4-二甲氨基苯基)偶氮]-1-苄基-吡啶阳离子和镍-双-1,2-二硫烯阴离子合成了离子对配合物1和2,并且对2个配合物进行了晶体结构和磁性质的研究。晶体1和2中,阴阳离子呈柱状交替排列堆积。在2~300 K温度范围内,配合物1具有反铁磁性(θ=-0.016 2 K),配合物2在110 K左右具有spin-gap现象(Δ/κb=38 915.42 K)。 |

Abstract: The crystal structures and magnetic properties were investigated for two ion-pair complexes, which consisted of [Ni(mnt)2]- (mnt=1,2-dithiolene) with [2-[[4-(dimethylamino)phenyl]azo]-1-methyl-py]+ for complex 1 and [2-[[4-(dimethylamino)phenyl]azo]-1-benzyl-py]+ for complex 2. In complexes1 and 2, cations and anions stacked into segregated columns. Magnetic susceptibility measurements in temperature range 2~300 K showed that complex 1 exhibited an antiferromagnetic coupling feature with θ=-0.016 2 K, while 2 shows characteristic of spin-gap (Δ/κb=38915.42 K) around 110 K.
