چکیده
In the title compound, C(20)H(14)N(2)O(2)·C(3)H(7)NO, the quinoxaline ring forms dihedral angles of 64.9 (2) and 30.9 (2)° with the two substituted benzene rings, which are themselves inclined at 58.4 (2)°. An intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, mol-ecules are linked through inter-molecular O-H⋯O hydrogen bonds.

In the title complex, [Fe(C(19)H(12)BrClN(3)O(2))(C(3)H(7)NO)], the Fe(III) atom is coordinated by an N,N,O,O-tetra-dentate Schiff base ligand and trans coordinated by a chloride anion and the O atom of an N,N-dimethyl-formamide mol-ecule. The resulting geometry is distorted octa-hedral within a ClN(2)O(3) donor set.

The title compound, crystallized as a methanol solvate, C(18)H(20)O(2)·CH(3)OH, is an inter-mediate in the synthesis of the anti-lipidemic agent clinofibrate. Mol-ecules are packed together with the methanol solvent molecule via two O-H⋯O hydrogen bonds. The third O-H⋯O hydrogen bond is between neighboring 4,4'-(cyclo-hexane-1,1-di-yl)diphenol mol-ecules. The dihedral angle between two benzene ...

In the title compound, [Cu(C(20)H(10)Br(4)N(2)O(2))(C(3)H(7)NO)]·C(3)H(7)NO, the Cu(II) ion is coordinated by two N atoms and two O atoms from a tetra-dentate Schiff base ligand and the O atom of one dimethyl-formamide ligand in an almost square-pyramidal geometry. The uncoordinated dimethyl-formamide solvent mol-ecule is disordered over two sets of positions with occupancies of 0.741 (4) and 0...

In the crystal struture of the title compound, C(16)H(14)O(6)·C(3)H(7)NO, the two crystallographically independent benzene rings are coplanar [dihedral angle = 1.00 (2)°]. The crystal structure is stabilized by O-H⋯O hydrogen bonds between the diacid and the solvate dimethylformamide mol-ecule, resulting in the formation of a zigzag chain structure extending parallel to [001].
