title: Bis(4,4''-difluoro-1,1':3',1''-terphenyl-2'-carboxyl-ato-κO)tetra-kis-(methanol-κO)calcium methanol tetra-solvate.
abstract: In the title compound, [Ca(C(19)H(11)F(2)O(2))(2)(CH(3)OH)(4)]·4CH(3)OH, the Ca(2+) ion is located on an inversion centre and is hexa-coordinated by two O atoms of two 4,4''-difluoro-1,1':3',1''-terphenyl-2'-carboxyl-ate ligands and four O atoms of four methanol ligands, forming a CaO(6) polyhedron with a slightly distorted octa-hedral coordination geometry. The Ca-O-C angle between the carboxyl-ate group and the calcium ion is 171.8 (2)°. Two types of inter-molecular hydrogen-bond inter-actions (C=O⋯H and O-H⋯O) between the carboxyl-ate ligand, the methanol solvent mol-ecules and the coordinating methanol ligands generate a two-dimensional network parallel to (001).
