In the centrosymmetric dinuclear title compound, [Cd2I 4(C12H12N2O2) 2], two -I atoms bridge two CdII atoms and each Cd II atom is also bonded to a terminal I atom and a hy-droxy-meth-oxy-bis-(2-pyrid-yl)methane ligand, which functions in an N,O,N′-tridentate mode, resulting in a distorted octa-hedral coordination environment. Inter-molecular O - H⋯I hydrogen bonds and π-π stacking inter-actions between the pyridine rings [centroid-centroid distance = 3.790 (2) Å] are present in the crystal structure.

In the title compound, [Zn(NO3)2(C7H 9NO)2], the ZnII atom, lying on a twofold rotation axis, is six-coordinated in a distorted octa-hedral geometry by two N atoms and two O atoms from two (2-amino-phenyl)methanol ligands and two O atoms from two monodentate nitrate anions. Inter-molecular N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds stabilize the crystal structure.

In the title compound, [Mn(NO3)2(C7H 9NO)2], the MnII atom (site symmetry 2) is coordinated by two N,O-bidentate (2-amino-phenyl)methanol ligands and two monodentate nitrate anions in a distorted cis-MnN2O4 octa-hedral coordination geometry. In the crystal, N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds help to establish the packing.

The asymmetric unit of the title compound, [Co(NO3) 2 -(C7H9NO)2], contains one-half of the molecule. The CoII atom (site symmetry 2) is six-coordinate in a distorted octahedral configuration bonded by two N and two O atoms from two (2-aminophenyl)methanol ligands and two O atoms from the two nitrate anions. Crystal packing is stabilized by intermolecular N-H⋯O, O-H⋯O and C-H⋯O hydrogen-bonding inter-actions.

In the mol-ecule of the title compound, [ZnBr2(C 10H8N2)(C2H6OS)], the ZnII atom is five-coordinated in a distorted trigonal-bipyramidal configuration by two N atoms from one 2,2′-bipyridine, one O atom from one dimethyl-sulfoxide molecule and two Br atoms. Inter-molecular π-π stacking between parallel pyridine rings [face-to-face distance 3.32 (4) Å] and C - H⋯Br and C - H⋯O hydrogen-bonding interactions are present in the crystal structure.
