Bis[(E)-4-(hydroxy-imino-meth-yl)pyridinium] oxalate.

ABSTRACT: The formula unit of the title compound, 2C(6)H(7)N(2)O(+)·C(2)O(4) (2-), comprises two symmetry-equivalent 4-(hydroxy-imino-meth-yl)-pyridinium cations on general positions, linked through hydrogen bonding via an oxalate anion that resides on a crystallographic centre of symmetry. The crystal structure consists of infinite chains of cations and oxalate anions directed by O-H⋯O and multicentre N-H⋯O inter-molecular hydrogen-bonding inter-actions.

Project description: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 species.

Project description:In the title complex, [Mn(C(12)H(16)NO(5))(2)]·2CH(3)OH·0.5H(2)O, the Mn(II) atom has a distorted octa-hedral coordination geometry in which two N atoms from two 6-meth-oxy-2-[tris-(hydroxy-meth-yl)methyl-imino-meth-yl]phenolate ligands adopt a trans arrangement. The Mn-O(H) bonds (mean length 2.134?Å) are significantly longer than the Mn-O and Mn-N bonds (mean length 2.011 and 2.027?Å, respectively), and the dihedral angle between the mean planes through the aromatic rings of the two ligands is 76.8?(1)°. A complex network of O-H?O hydrogen bonds is formed between the complexes and the uncoordinated methanol and water mol-ecules. The C and O atoms of one C-OH group are disordered with equal occupancies.

Project description:In the title compound, [Ni(C(12)H(16)NO(5))(2)]·2H(2)O, the Ni(II) atom is coordinated by four O atoms and two N atoms from the two 6-meth-oxy-2-{[tris-(hydroxy-meth-yl)meth-yl]imino-meth-yl}phenolate ligands in a distorted octa-hedral coordination geometry.

(2-{[1,1-Bis(hydroxy-meth-yl)-2-oxidoeth-yl]imino-meth-yl}-4-chloro-phenolato-κN,O,O')dibutyl-tin(IV).

Project description:The Schiff base ligand in the title compound, [Sn(C(4)H(9))(2)(C(11)H(12)ClNO(4))], chelates to the Sn atom through the two deprotonated O atoms, as well as through the N atom, to confer an overall cis-C(2)SnNO(2) trigonal-bipyramidal geometry at tin [C-Sn-C = 130.3 (1)°]. The hydr-oxy groups engage in O-H⋯O hydrogen bonding with the O atoms of adjacent mol-ecules, generating a chain running along the c axis.

Bis{μ-2-meth-oxy-6-[(methyl-imino)-meth-yl]phenolato}bis-({2-meth-oxy-6-[(methyl-imino)-meth-yl]phenolato}copper(II)).

Project description:The title compound, [Cu2(C9H10NO2)4], is built of discrete centrosymmetric dimers. The Cu(II) atoms are each five coordinated by two deprotonated Schiff base ligands that are bonded differently to the metal atoms. Of the two phenolate O atoms, one is coordinated to one Cu(II) atom, whereas another bridges the two metal atoms. The basal plane of the square pyramid around Cu(II) atoms is formed by the imino N and phenolate O atoms of the bidentate and the monodentate/bidentate Schiff base ligands. The bridging phenolate oxygen occupies the apical position of the coordination sphere with a considerably longer Cu-O bond length. In the crystal, the dimeric mol-ecules pack relative to each other in such a way that the Cu2O2 planes of adjacent dimers are orthogonal.

4-Chloro-2-((E)-{3-[1-(hydroxy-imino)eth-yl]phen-yl}imino-meth-yl)phenol.

Project description:The title compound, C(15)H(13)ClN(2)O(2), adopts an E conformation with respect to the azomethine C=N bond. The aniline and phenol rings are almost coplanar, making a dihedral angle of 3.33 (2)°. In the crystal, the mol-ecules lie about inversion centers, forming dimers that are connected by inter-molecular O-H⋯N hydrogen bonds, resulting in six-membered rings with graph-set motif R(2) (2)(6). In addition, there is a strong inter-molecular O-H⋯N hydrogen-bonding inter-action, resulting in an S(6) ring motif. Weak π-π inter-actions between the benzene rings [centroid-centroid distance = 3.809 (1) Å] further stabilize the crystal structure.

Project description:In the title compound, C(15)H(13)BrN(2)O(2), he oxime unit adopts an E conformation with respect to the O-H group.

The crystal structure is stabilized by inter-molecular O-H⋯N hydrogen bonds between the hydr-oxy groups and the oxime N atoms. In addition, the crystal structure also features short inter-molecular Br⋯Br short contacts with a distance of 3.8768 (5) Å.

Tetra-kis(μ(3)-2-{[1,1-bis-(hydroxy-meth-yl)-2-oxidoeth-yl]imino-meth-yl}-6-methoxy-phenol-ato)tetra-nickel(II) tetra-hydrate.

Project description:The title complex, [Ni(4)(C(12)H(15)NO(4))(4)]·4H(2)O, has crystal-lographic fourfold inversion symmetry, with each Ni(II) ion coordinated in a slightly distorted square-pyramidal coordination environment and forming an Ni(4)O(4) cubane-like core. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds connect complex and water mol-ecules to form a three-dimensional network. The O atom of one of the unique hydroxy-methyl groups is disordered over two sites, with the ratio of occupancies being approximately 0.79:0.21.
