The mesomerically stabilised anion tris(diphenylphosphinoyl)methanide reacts with yttrium(also scandium, lutetium, and praseodymium ) chloride to from tris[tris(diphenylphosphinoyl)methanido]yttrium in which the ligand is bidentate and kinetically inert on an n.m.r. time-scale at room temperature and from whose 31P n.m.r. spectrum a 89Y–31P nuclear spin coupling constant can be determined.
介观稳定的阴离子三(二苯基膦酰基)甲甲烷与钇(also,和ase)氯化物反应生成三(三(二苯基膦酰基)甲酰氨基]钇,其中配体是二齿的,在室温下在nmr时间尺度上呈动力学惰性温度和其31 P nmr光谱可确定89 Y– 31 P核自旋耦合常数。
