ABSTRACT: In the title compound, C17H20Cl2N4O, the piperazine ring adopts a chair conformation and the dihedral angle between the pyridazine ring and the benzene ring is 36.3 (1)°. In the crystal, weak C—H...O and C—H...(N,N) interactions help to establish the packing, which also features short intermolecular Cl...Cl contacts [3.331 (2) Å].

ABSTRACT: In the title compound, C33H32ClNO2, the benzene ring is oriented at dihedral angles of 6.23 (5) and 66.44 (5)° with respect to the two naphthalene ring systems. An intramolecular O—H...N hydrogen bond between the hydroxy H atom and the amine N atom generates an S(6) ring.

ABSTRACT: In the title compound, C10H18N3OS+·Cl−·2H2O, the three C atoms of the isopropyl group are disordered and were refined using a split-site mode [occupancy ratio 0.53 (3):0.47 (3)]. In the crystal, the cations, anions and water molecules are connected via O—H...O, O—H...Cl, N—H...Cl and N—H...O hydrogen bonding.
