Three uranium(IV)-alkyl phosphato complexes U(O2P(OR)2)4 (R = Me, Et, nBu), four uranium(IV)-alkyl phosphonato complexes U(O2PHOR)4 (R = Me, Et, iPr, nBu) and a uranium(IV) bis(phenyl phosphonato) complex U(O3PC6H5)2 were prepared and their magnetic susceptibilities measured over the temperature range 4.2–300 K. All eight complexes showed normal paramagnetic behavior. Far infrared spectra were used
三个铀(IV) -烷基磷酸根合络合物ù(O 2 P(OR)2)4(R =甲基,乙基,Ñ丁基),四个铀(IV) -烷基膦络合物ù(O 2普)4(R = Me,Et,i Pr,n Bu)和铀(IV)双(苯基膦酸)络合物U(O 3 PC 6 H 5)2制备了它们,并在4.2-300 K的温度范围内测量了它们的磁化率。所有八种配合物均显示出正常的顺磁行为。远红外光谱用于推断这些聚合物固体的U(IV)配位球的结构。根据晶体场理论计算出的磁化率与实验数据吻合良好。
