Crystal structure of tetra-kis-(1-oxidopyridin-2-yl)methane methanol tetra-solvate.

ABSTRACT: The asymmetric unit of the title compound, C21H16N4O4·4CH3OH, consists of a quarter mol-ecule of tetra-kis-(1-oxidopyridin-2-yl)methane and one methanol solvent mol-ecule. In the crystal, the pyridine N-oxide derivative is located about a fourfold rotoinversion axis and exhibits S 4 symmetry along the c axis. An inter-molecular O-H⋯O hydrogen bond is observed between the O atom of the pyridine N-oxide and the OH group of the methanol. An inter-molecular C-H⋯O bond is also observed between adjacent pyridine N-oxide rings.
