4-Bromo-2-({4-[(hy-droxy-imino)-meth-yl]phen-yl}imino-meth-yl)phenol.

In the title compound, C(14)H(11)BrN(2)O(2), the mean planes of the two benzene rings are almost parallel to each other, making a dihedral angle of 4.09 (1)°. An intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, inter-molecular O-H⋯N and C-H⋯O hydrogen bonds link the mol-ecules into a chain-like supra-molecular structure.

4-[(Ethoxy-imino)(phen-yl)meth-yl]-5-methyl-2-phenyl-1H-pyrazol-3(2H)-one.

In the mol-ecule of the title compound, C(19)H(19)N(3)O(2), the central pyrazole ring makes dihedral angles of 9.89 (3) and 66.06 (5)° with the two phenyl rings, and the two phenyl rings form an angle of 74.05 (5)°. An intra-molecular C-H⋯O hydrogen bond forms a six-membered ring, producing an S(6) ring motif. In the crystal structure, inter-molecular N-H⋯O and C-H⋯O hydrogen bonds link each mol-ecule to two others, forming an infinite one-dimensional supra-molecular structure along the c axis.
