1.  Di-tert-butyl 3,5-dimethyl-1H-pyrrole-2,4-dicarboxyl­ate 
In the title mol­ecule, C16H25NO4, the non-H atoms, except for the two tert-butyl groups, are roughly planar (r.m.s. deviation of the non-H atoms = 0.086 Å). In the crystal, mol­ecules are linked into inversion dimers by pairs of N—H⋯O hydrogen bonds, forming R 2 2(10) ring motifs.

2.  2,2′-Dichloro-N,N′-[1,3-phenyl­enebis(methyl­ene)]diacetamide 
The complete mol­ecule of the title compound, C12H14Cl2N2O2, is generated by a crystallographic twofold axis with two C atoms of the central benzene ring lying on the axis. In the crystal, N—H⋯O hydrogen bonds link the mol­ecules into chains parallel to the c axis.

3.  3-Methyl-4-{[(3-{[(3-methyl-5-oxo-1-phenyl-4,5-dihydro-1H-pyrazol-4-yl­idene)(phen­yl)meth­yl]amino­meth­yl}benz­yl)amino](phen­yl)methyl­idene}-1-phenyl-1H-pyrazol-5(4H)-one 
The complete mol­ecule of the title compound, C42H36N6O2, is generated by a crystallographic twofold axis with two C atoms of the central phenyl group lying on the axis. In the independent part of the mol­ecule, one amino group is involved in an intra­molecular N—H⋯O hydrogen bond, and the two adjacent phenyl rings are twisted from the plane of the pyrazolone ring with dihedral angles of 6.82 (3) and 88.32 (6)°. The crystal packing exhibits no classical inter­molecular contacts.

7.  2-Chloro-N-methyl-N-phenyl­acetamide 
In the title compound, C9H10ClNO, the non-H atoms, excluding the phenyl group, are almost coplanar (r.m.s. deviation of the non-H atoms = 0.1015 Å). The dihedral angle formed between this plane and the benzene ring is 87.07 (5)°. Weak inter­molecular C—H⋯O inter­actions help to stabilize the packing.

8.  Ethyl 3,4-dimethyl-1H-pyrrole-2-carboxyl­ate 
The non-H atoms of the title compound, C9H13NO2, are almost coplanar (r.m.s. deviation = 0.0358 Å). Weak inter­molecular N—H⋯O hydrogen bonds link the mol­ecules into zigzag chains along the b axis with graph-set motif C(5). The chains are further linked into a three-dimensional network by C—H⋯O hydrogen bonds and C—H⋯π inter­actions.

9.  Ethyl 3,4-dimethyl-5-[(E)-(phenyl­imino)­meth­yl]-1H-pyrrole-2-carboxyl­ate 
In the title compound, C16H18N2O2, the mol­ecule adopts an E conformation about the C=N double bond. The dihedral angle between the pyrrole and phenyl rings is 41.55 (8)°. In the crystal structure, pairs of inter­molecular N—H⋯O hydrogen bonds link the mol­ecules into centrosymmetric dimers. In the dimer, the two pyrrole rings are almost coplanar and the two phenyl rings are parallel to each other.

10.  Bis[N-benzyl-2-(quinolin-8-yl­oxy)acetamide]dichloridocopper(II) acetonitrile solvate monohydrate 
In the title complex, [CuCl2(C18H16N2O2)2]·CH3CN·H2O, the six-coordinated Cu atom is in a distorted octa­hedral geometry with the donor centers of two O atoms and two N atom from two bidentate ligands, and two chloride ions. In the crystal, pairs of inter­molecular N—H⋯ Cl hydrogen bonds form centrosymmetric dimers and inter­molecular O—H⋯ O hydrogen bonds between the ligand and the uncoordinated water mol­ecules link the dimers into chains parallel to the c axis.
