以氯化锰、双二苯基膦酸甲烷(dppm)及7,7,8,8-四氰基对醌二甲烷(TCNQ)为原料,合成了标题化合物[Mn(dppmdo)_3][(TCNQ)(DCBE)]1;利用X射线衍射、红外光谱、紫外-可见-近红外光谱和循环伏安等技术对合成产物进行了表征.结果表明,化合物1在近红外区发生配体TCNQ之间的电子转移(TCNQ/TCNQ~-).化合物1中的TCNQ比游离态的TCNQ分子更容易被还原.室温下,化合物1的有效磁矩(12.7μB)远高于预期的由一个高自旋Mn~(2+)离子(S=5/2)、一个TCNQ(S=1/2)阴离子及一个DCBE(S=1/2)阴离子组成基团的有效磁矩(4.58μB),表明它们之间存在着很强的磁相互作用.
The title compound [Mn (dppmdo) _3] [((1)) was synthesized from manganese chloride, diphenylphosphonic acid methane (dppm) and 7,7,8,8-tetracyanoquinodimethane (TCNQ) TCNQ) (DCBE)] 1 was synthesized and characterized by X-ray diffraction, FTIR, UV-Vis-NIR and cyclic voltammetry.The results showed that compound 1 produced ligand TCNQ in the near infrared region (TCNQ / TCNQ ~) .The TCNQ in compound 1 is more easily reduced than the free TCNQ molecule.The effective magnetic moment (12.7μB) of compound 1 at room temperature is much higher than that expected by a highly spinnable Mn ~ The effective magnetic moments (4.58 μB) for the (2+) ions (S = 5/2), one TCNQ (S = 1/2) anion and one DCBE (S = 1/2) anion make up the difference between There is a strong magnetic interaction.
