چکیده
The title Schiff base, C(11)H(14)ClNO(4), originally refined as a neutral mol-ecule [Chumakov, Antosyak, Mazus, Tsapkov & Samus (2000), Crystallogr. Rep.45, 945-950], is inter-preted as a zwitterionic compound. There are two independent zwitterions in the asymmetric unit. Five of the six hydr-oxy groups of the -CH(2)OH fragments are disordered. In one zwitterion, two are disordered over three sites [0.53 (1):0.33 (1):0.14 (1) and 0.65 (1):0.18 (1):0.17 (1)] and the third over two sites [0.66 (1):0.34 (1)]. In the second zwitterion, two are disordered over two sites [0.84 (1):0.16 (1) and 0.83 (1):0.17 (1)] and the third hydr-oxy group is ordered.

In the title compound, [Cu(C(12)H(16)NO(5))(2)]·2H(2)O, the Cu(II) ion adopts a trans-CuN(2)O(4) octa-hedral geometry arising from two N,O,O'-tridentate 6-meth-oxy-2-{[tris-(hydroxy-meth-yl)meth-yl]-imino-meth-yl}phenolate ligands. The Jahn-Teller distortion of the copper centre is unusally small. In the crystal structure, O-H⋯O hydrogen bonds, some of which are bifurcated, link the component s...

In the title compound, [Mn3(C14H12ClN2O)3(CH3O)3O]ClO4·1.1CH2Cl2·0.9C4H10O, the cation consists of a central Mn3O core with μ2-methano-late bridging between adjacent MnIII atoms, thus giving each MnIII atom a mer-O3 coordination environment. Six-coordination for each MnIII atom is provided by the deprotonated Schiff base ligand (E)-4-chloro-2-({[2-(pyridin-2-yl)eth-yl]imino}-meth-yl)phenolate. ...
