Manganese(II) tetrahedral complexes having general formula [MnX₂L₂] (X = Cl, Br, I; L = 1,3-dimethyl-2-phenyl-1,3-diazaphospholidine-2-oxide) were isolated and characterized. The structures of the chloro- and bromo-derivatives were ascertained by single-crystal X-ray diffraction. The three species are appreciably luminescent in the green region upon excitation with UV light. The luminescence lifetimes are strongly dependent upon the choice of the coordinated halide. The rigid 1,3-diazaphospholidine-2-oxide moiety improved the photoluminescence features with respect to comparable phenylphosphonic diamide Mn(II) derivatives.

四面体光致发光锰（ii）卤化物与1,3-二甲基-2-苯基-1,3-二氮杂磷吡啶-2-氧化物作为配体的配合物†

分离并表征了具有通式[MnX ₂ L ₂ ]（X = Cl，Br，I； L = 1,3-二甲基-2-苯基-1,3-二氮杂磷腈-2-氧化物）的锰（II）四面体配合物。通过单晶X射线衍射确定氯和溴衍生物的结构。当用紫外光激发时，这三种物质在绿色区域中明显发光。发光寿命在很大程度上取决于配位卤化物的选择。相对于可比较的苯基膦二酰胺Mn（II）衍生物，刚性的1，3-二氮杂膦基-2-氧化物部分改善了光致发光特征。
