In the title complex, [Cu(C7H5O3)2(C7H6N2)2], (I), the CuII atom, located on an inversion center, is surrounded by two 4-hydroxybenzoate anions and two benzimidazole molecules in an elongated octahedral geometry, the longer Cu—O distance being 2.618 (2) Å in the axial direction. The partially overlapped arrangement and the short face-to-face distance of 3.405 (6) Å suggest π–π stacking between benzimidazole ligands of neighboring molecules.

The racemic title compound, C30H32N2O4, was synthesized from spiro[2H-1,3-benzoxazine-2,1′-cyclohexan]-4(3H)-one and N-benzylidene-2-methoxybenzenamine under classical Reformatsky reaction conditions. Intermolecular N—HO and C—HO hydrogen bonds link the molecules in the crystal structure into infinite chains along the a axis. These chains form layers parallel to the (001) plane, which are stabilized by weak interlayer C—HO hydrogen bonds.

The title complex, [Co(C7H5O3)2(C12H8N2)(H2O)2]·H2O, displays a distorted octahedral coordination geometry about the CoII atom, involving two 4-hydroxybenzoate anions, one 1,10-phenanthroline (phen) molecule and two water molecules. The face-to-face distance of 3.420 (5) Å between partially overlapped parallel phen rings reflects a π–π stacking interaction between neighboring CoII complex molecules. A network of O—HO hydrogen bonds helps to stabilize the crystal packing.

The asymmetric unit of the title compound, di-μ-aqua-1:2κ4O:O-triaqua-1κ3O-dilosartanido-1κN;2κ2N,N′-dipotassium dihydrate, [K2(C22H22ClN6O)2(H2O)5]·2H2O, is composed of two losartan anions, two K+ cations and seven water molecules. Some water molecules bridge the potassium ions linking the molecules to form an infinite chain. The two potassium ions have different environments; one is six-coordinated by three water O atoms and three tetrazole N atoms, whereas the other is five-coordinated by five water O atoms. Extensive hydrogen-bonding interactions lead to a three-dimensional structure.
