Tetrahedral Mn(II) bromo- and iodo-complexes with phosphoramidate and phosphonate ligands were synthesized and characterized. Mononuclear complexes with the general formula [MnX2L2] were isolated by using the monodentate ligands OP(OPh)2(NMe2) and OP(OPh)2Ph. The bidentate resorcinol derivative 1,3-OP(NMe2)O–C6H4–O(NMe2)2PO behaved as a bridging ligand, and afforded, by reaction with MnX2 salts, a
合成并表征了具有氨基磷酸酯和膦酸酯配体的四面体 Mn( II ) 溴和碘配合物。通过使用单齿配体O P(OPh) 2 (NMe 2 ) 和O P(OPh) 2 Ph分离出通式为[MnX 2 L 2 ] 的单核配合物。双齿间苯二酚衍生物1,3-O P(NMe 2 )O–C 6 H 4 –O(NMe 2 ) 2 P O 表现为桥连配体,并通过与 MnX 2反应得到盐,X = Br 情况下的双核配合物和 X = I 的配位聚合物,如单晶 X 射线衍射所示。所有化合物在四面体环境中均显示出 Mn( II )的特征性绿色光致发光。所得寿命值受化合物对称性的影响。在配位球中与 O P(OPh) 2 (NMe 2 ) 的配合物显示出高光致发光量子产率。
