solvent being easily removed in vacuo. The crystal structures of the complexes [LnS2PR2}4] [AsPh4] have been determined from diffractometer data for Ln = Ce and Er, R = OMe; and Ln = Nd and Ho, r = OPri. [CeS2P(OMe)2}4] [AsPh4]: monoclinic, space group Cc with a = 14.762(3), b = 16.780(4), c = 19.890(3) A and β = 101.09(1)°, R = 0.041. [ErS2P(OMe)2}4] [AsPh4]: isomorphous to the above with a = 14.626(3)
摘要镧系元素离子与二硫代磷酸R2PS2H(R = OMe,OPri)的盐在相应的醇中反应形成四价阴离子络合物,可以将其分离为四苯基ar盐。对于R = OPri,重离子的配合物结晶为溶剂化物,溶剂很容易在真空中除去。配合物[Ln S2PR2} 4] [AsPh4]的晶体结构已经由衍射仪数据确定,其中Ln = Ce和Er,R = OMe;并且Ln = Nd和Ho,r = OPri。[Ce S2P(OMe)2} 4]:[AsPh4]:单斜空间群Cc,a = 14.762(3),b = 16.780(4),c = 19.890(3)A,β= 101.09(1)° ,R = 0.041。[Er S2P(OMe)2} 4]:[AsPh4]:与上述同构,a = 14.626(3),b = 16.760(2),c = 19.718(1)A,β= 100.89(1)°, R = 0.056。[Nd S2P(OPri)2}
