An ion pair uniting a gadolinium(III)-Schiff base complex and uranyl tetrachloride.
The Schiff base N-(tert-butyl)-3-methoxysalicylaldimine (LH) forms a complex with gadolinium(III) chloride, [GdCl(2)(LH)(2)(C(5)H(5)N)(2)](+), in which the two O atoms of each ligand are coordinated (the phenolic O atom being deprotonated) and the imine N atom is protonated and involved in a hydrogen bond with the phenoxide group. This complex crystallizes as an ion pair with uranyl tetrachloride, i.e. bis(bis[2-(tert-butyliminiomethyl)-6-methoxyphenolato-O,O']dichlorobis(pyridine-N)gadolinium(III)) tetrachlorodioxouranium(VI) tetrapyridine solvate [GdCl(2)(C(12)H(17)NO(2))(2)(C(5)H(5)N)(2)](2)[UCl(4)O(2)].4C(5)H(5)N. The U atom of the UCl(4)O(2) anion lies on an inversion centre.
