Dimethyl 4-[3-(4-meth-oxy-phen-yl)-1-phenyl-1H-pyrazol-4-yl]-2,6-dimethyl-1,4-dihydro-pyridine-3,5-dicarboxyl-ate dihydrate.

In the title compound, C(27)H(27)N(3)O(5)·2H(2)O, the dihydro-pyridine ring adopts a flattened boat conformation. The central pyrazole ring is essentially planar [maximum deviation of 0.003 (1) Å] and makes dihedral angles of 50.42 (6) and 26.44 (6)° with the benzene rings. In the crystal, mol-ecules are linked via N-H⋯O, O-H⋯O, O-H⋯N and C-H⋯O hydrogen bonds into two-dimensional networks parallel to the bc plane. The crystal structure is further consolidated by weak C-H⋯π inter-actions.

Dimethyl 2,6-dimethyl-4-(3-phenyl-1H-pyrazol-4-yl)-1,4-dihydro-pyridine-3,5-dicarboxyl-ate.

In the title compound, C(20)H(21)N(3)O(4), the 1,4-dihydro-pyridine ring adopts a boat conformation. An intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif. The pyrazole ring makes dihedral angles of 87.81 (7) and 45.09 (7)° with the mean plane of the 1,4-dihydro-pyridine ring and the phenyl ring, respectively. In the crystal, mol-ecules are linked by N-H⋯N, N-H⋯O and C-H⋯O hydrogen bonds into a three-dimensional network.

4-[3-(Biphenyl-4-yl)-1-phenyl-4,5-di-hydro-1H-pyrazol-5-yl]-3-(4-meth-oxy-phen-yl)-1-phenyl-1H-pyrazole dioxane monosolvate.

In the title compound, C(37)H(30)N(4)O·C(4)H(8)O(2), the dihedral angle between the pyrazole and dihydro-pyrazole rings is 74.09 (10)°. In the crystal, the components are linked into centrosymmetric tetra-mers (two main mol-ecules and two solvent mol-ecules) by C-H⋯O hydrogen bonds. C-H⋯π and π-π [shortest centroid-centroid separation = 3.6546 (9) Å] inter-actions are also observed.
