In the title compound, C(13)H(9)BrClNO, the dihedral angle between the substituted benzene rings is 43.90 (11)°. Strong intra-molecular O-H⋯N hydrogen bonds generate S(6) ring motifs. The crystal structure features short intemolecular Br⋯Br [3.554 (2) Å] and Cl⋯Cl [3.412 (2) Å] contacts. The crystal packing is further stabilized by inter-molecular C-H⋯O and C-H⋯π inter-actions.

The title compound, CHBrNO, is chiral at the carbon atoms on either side of the oxygen atom of the oxazolidine ring and crystallizes as a racemate. The 1,3-oxazolidine ring adopts an envelope conformation with the N atom in an position. The mean plane of the oxazolidine ring makes dihedral angles of 77.

A full understanding of the assembly mechanisms of coordination complexes is of great importance for a directional synthesis under control. We thus explored here the formation mechanisms of the two new heterometallic nanoclusters [DyNi(μ-OH)(L)(OAc)(HO)]·3.25EtOH·4CHCN () and [DyMnMnO(OH)(OAc)(L)(HL)(EtOH)]·2EtOH·2CHCN·2HO () with different cubane-based squarelike ring structures, which were obtained from the reactions of 4-bromo-2-[(2-hydroxypropylimino)methyl]phenol (HL) with Dy(NO)·6HO and the transition metal salt Ni(OAc)·4HO or Mn(OAc)·4HO.

The synthesis and crystal structure (100 K) of the title compound, [Fe(CHBrNOS)]NO·HO, is reported. The asymmetric unit consists of an octahedral [Fe(HL)] cation, where HL is H-5-Br-thsa-Et or 5-bromosalicylaldehyde 4-ethylthiosemicarbazonate(1-) {systematic name: 4-bromo-2-[(4-ethylthiosemicarbazidoidene)methyl]phenolate}, a nitrate anion and a noncoordinated water molecule. Each HL ligand binds via the thione S, the imine N and the phenolate O atom, resulting in an FeSNO chromophore.

The new title Schiff base compound, CHBrNO, crystallizes in the monoclinic space group 2 with two independent mol-ecules in the asymmetric unit. It was prepared by the condensation reaction of 5-bromo-2-hy-droxy-benzaldehyde and amino-ethyl-ethano-lamine. There is an intra-molecular O-H⋯N hydrogen bond with an (6) ring motif.

A new bidentate Schiff base ligand (ATBS [4-bromo-2-(thiazole-2-yliminomethyl)phenol]) was synthesized via the condensation reaction of 2-aminothiazole with 5-bromosalicylaldehyde in ethanol. The reaction of ATBS with transition metal salts of Cu(II), Co(II), Ni(II), and Mn(II) afforded the corresponding ATBS-M complexes. Results from physicochemical and spectral analyses, such as elemental analysis, infrared, UV-Vis spectroscopy, magnetic susceptibility, and molar conductance, revealed a nonelectrolytic nature with octahedral (O ) geometry and a metal/ligand ratio of 1:2 for Cu(II), Co(II), and Ni(II), but 1:1 for the Mn(II) complex.
