چکیده
In the title compound, C(21)H(26)N(2)O(2), the dihedral angle between the two benzene rings is 73.47 (16)°. Strong intra-molecular O-H⋯N hydrogen bonds generate S(6) ring motifs. The substituted benzene rings are twisted around the central quaternary C atom in opposite directions, making a vault geometry.

Two distinct coordination geometries are found in the binuclear title complex, [Ni(2)(C(13)H(19)N(2)O(2))(2)(N(3))(2)(CH(3)OH)], as one Schiff base ligand is penta-dentate, coordinating via the anti-cipated oxide O, imine N and amine N atoms (as for the second, tridentate, ligand) but the oxide O is bridging and coordination also occurs through the meth-oxy O atom. The Ni(II) atoms are linked b...

The asymmetric unit of the title compound, C(19)H(18)I(4)N(2)O(2), comprises a potentially tetra-dentate Schiff base ligand. The disordered H atoms on the N and O atoms were refined with site occupancies of 0.54 (8)/0.46 (8) and 0.59 (7)/0.41 (7), respectively. The dihedral angle between the benzene rings is 73.3 (3)°. Intra-molecular O-H⋯N and N-H⋯O hydrogen bonds make S(6) ring motifs. Short ...

The reaction between copper(II) nitrate and (E)-N-(3-amino-2,2-dimethyl-prop-yl)-2-(hy-droxy-imino)-propanamide led to the formation of the dinuclear centrosymmetric copper(II) title complex, (C8H18N3O2)2[Cu2(C8H15N3O2)2(C8H17N3O2)2](C9H16N3O4)2·2CH3CN, in which an inversion center is located at the midpoint of the Cu2 unit in the center of the neutral [Cu2(C8H15N3O2)2(C8H17N3O2)2] complex frag...

The complete mol-ecule of the title complex, [Cu(2)(C(13)H(19)N(2)O(2))(2)(N(3))(2)], is generated by the application of a centre of inversion. The central Cu(2)N(2) core is a rhombus as the μ(2)-azide ligands bridge in an asymmetric fashion. Each Cu(II) atom is also coordinated by a monoanionic tridentate Schiff base ligand via the anti-cipated oxide O, imine N and amine N atoms. The resulting...

The title compound, C(12)H(10)N(4)O, is a Schiff base obtained from the condensation of diamino-maleonitrile and 2-hy-droxy-3-methyl-benzaldehyde. The mol-ecule is roughly planar, with an r.m.s. deviation of 0.0354 Å, and adopts the phenol-imine tautomeric form. An intra-molecular O-H⋯N hydrogen bond involving the O-H group and the azomethine N atom generates an S(6) ring. In the crystal, there...
