The title compound, [HgCl2(C14H12N2)], consists of one 2,9-dimethyl-1,10-phenanthroline (dmphen) ligand chelating the HgII ion and two chloride ligands coordinating to the HgII ion, forming a distorted tetrahedral environment. The dmphen ligand is nearly planar (r.m.s. deviation = 0.0225 Å). The dihedral angle between the normal to the plane defined by the HgII atom and the two Cl atoms and the normal to the plane of the dmphen ring is 81.8 (1)°.

In the title compound, C15H14O3, the dihedral angle between the benzene rings is 75.85 (7)°. In the crystal, centrosymmetrically related molecules are weakly associated through pairs of interactions between a benzene ring and an O atom of the ester group [ring centroidO = 3.952 (7) Å], and through pairs of interactions between the other benzene ring and an O atom of the phenoxy group [ring centroidO = 3.912 (7) Å], giving chains extending along [110].

In the title racemic Schiff base ligand, C20H20Cl2N2, which was prepared by the condensation of 2-chlorobenzaldehyde and cyclohexane-1,2-diamine, the cyclohexane ring adopts a chair conformation and the dihedral angle between the aromatic rings of the 2-chlorophenyl substituent groups is 62.52 (8)°. In the structure, there are two short intramolecular methine C—HCl interactions [CCl = 3.066 (2) and 3.076 (3) Å], and in the crystal there are also weak intermolecular aromatic C—HCl [3.464 (3), 3.553 (3) and 3.600 (3) Å] and ClCl [3.557 (3) and 3.891 (3) Å] contacts.

There are two independent molecules in the asymmetric unit of the title compound, C12H9ClN2OS, a Schiff base derived from hydrazide, in which the dihedral angles between the thiophene and benzene rings are 3.6 (3) and 7.3 (3)°. In the crystal, the two independent molecules are arranged about an approximate non-crystallographic inversion center and are connected by two N—HO hydrogen bonds. Weak C—HCl contacts are also present. Conversely, there are neither significant aromatic stacking interactions nor contacts involving S atoms.
