高价磷化合物3，7-二叔丁基-5-氮杂-2，8-二氧杂-1-磷杂双环[3.3.0]辛-2，4，6-三烯（ADPO）与铬、钨、镍、钯金属中心形成加合物。所有四个新的加合物含有四面体磷原子作为ADPO单元折叠的结果。平面10-P-3ADPO分子的这种折叠以提供8-P-3中心用于与过渡金属中心配位是10-P-3ADPO和8-P-3ADPO之间的紧密能量平衡和磷-金属相互作用强度的结果。在均配型钯（II）配合物的情况下，观察到配位ADPO单元的二聚化。
Abstract The hypervalent phosphorus compound, 3,7-di-t-butyl-5-aza-2,8-dioxa-1-phosphabicyclo-[3.3.0]octa-2,4,6-triene (ADPO) forms adducts with chromium, tungsten, nickel and palladium metal centers. All four new adducts contain tetrahedral phosphorus atoms as a result of folding of the ADPO unit. This folding of the planar 10-P-3 ADPO molecule to provide an 8-P-3 center for coordination to the transition metal center is the result of the close energy balance between 10-P-3 ADPO and 8-P-3 ADPO and the strength of the phosphorus-metal interaction. In the case of a homoleptic palladium(II) complex, dimerizati on of the coordinated ADPO unit was observed.
