| Abstract: | he quaternary mixed anion complex of
lanthanide 3)phen)]2 was synthesized and its crystal structure was determined by Rigaku AFC
7R The crystal structure belongs to triclinic system with space group P1 , a=09650(2) nm,
b=12949(4) nm,c=08994(2)nm, =9537(3),=11105(2),=10287(2),V=10037(5) nm3, Dc=1758
gcm\{-3\}, Z=1, F(000)=528, (MoK)=2464 cm-1 The final R is 0024 for 3302 I>3(I) The four
CH3CH2COO- anions have two coordination modes Two CH3CH2COO- anions are
bidentatebridging coordination and another two are tridentatebridging coordination |
