The asymmetric unit of the title compound, C(16)H(16)N(2)O(2)·2H(2)O, contains one half-mol-ecule of diphenol and one water mol-ecule. The complete diphenol mol-ecule is generated by a crystallographic inversion centre. In the mol-ecule, the central C(meth-yl)-C=N-N=C-C(meth-yl) plane makes a dihedral angle of 8.88 (6)° with its adjacent benzene ring. In the crystal, the components are linked by O-H⋯N and O-H⋯O hydrogen bonds into a three-dimensional network. The crystal structure is further stabilized by a weak C-H⋯π inter-action.

A new cis-dihalo copper(II) complex, [Cu(HL)(Cl)].CHCN (1), where HL = (S)-2-(((2-(2-(pyridin-2-yl)-2H-benzo[e][1,3]oxazin-3(4H)-yl)ethyl)amino)methyl)phenol), was isolated by reacting copper(II) chloride dihydrate and the HL ligand (HL = 2,2'-((2-(pyridin-2-yl)imidazolidine-1,3-diyl)bis(methylene))diphenol) in a MeOH/CHCN (1:3 v/v) mixture. The complex formation occurred via the ligand modification during complexation, producing a unique structure containing 2H-benzo[e][1,3]oxazin, as observed from the single crystal X-ray structure determination.

In the centrosymmetric title compound, [CdNi(2)(C(17)H(16)N(2)O(2))(2)(HCOO)(2)(H(2)O)(2)]·2H(2)O, The Ni(II) cation is chelated by a 2,2'-[propane-1,3-diylbis(nitrilo-methanylyl-idene)]diphen-olate (salpn) anion, and further coordinated by a formate anion and a water mol-ecule in a distorted NiN(2)O(4) octa-hedral geometry. The Cd(II) cation, located on an inversion center, is coordinated by four deprotonated hy-droxy groups from two salpn anions and two carboxyl-ate O atoms from formate anions in a distorted octa-hedral geometry. Both formate and salpn anions bridge the Cd and Ni cations, forming a trinuclear complex.

The title complex, [Fe(2)(C(20)H(14)N(2)O(2))(2)O]·CH(4)O·2H(2)O, is composed of μ-oxido-bridged ferric 2,2'-[o-phenylene-bis(nitrilo-methylidyne)]diphenolate (salphen) dimers, one methanol mol-ecule and two H(2)O mol-ecules. Each iron(III) ion, surrounded by two coordinating N and O atoms from the salphen ligand and one bridging O atom, shows a five-coordinate square-pyramidal geometry. One of the two solvent water mol-ecules is disordered over three positions with occupancies of 0.
