Catena-Poly[1-butyl-3-methyl-imidazolium [[dichlorido(methanol-?O)(propan-2-ol-?O)lanthanate(III)]-di-?-chlorido]].

ABSTRACT: The title compound, (C(8)H(15)N(2))[LaCl(4)(CH(3)OH)(C(3)H(7)OH)], consists of one 1-butyl-3-methyl-imidazolium (BMI(+)) cation and one hexa-hedral tetra-chlorido(methanol)(propan-2-ol)lanthanate anion. The La(III) ion is eight-coordinate, with the La(III) ion bridged by a pair of Cl atoms, so forming chains propagating along the a-axis direction. Each La(III) ion is further coordinated by two isolated Cl atoms, one methanol and one propan-2-ol mol-ecule. The coordinated methanol and propan-2-ol mol-ecules of the anion form O-H?Cl hydrogen bonds with the Cl atoms of inversion-related anions. The BMI(+) cation froms C-H?Cl hydrogen bonds with the Cl atoms of the anion. The anions are located in the C faces of the triclinic unit cell, with an inversion center in the middle of the La(2)Cl(2) ring of the polymeric chain.
