3,3'-Dimeth-oxy-2,2'-[(4,5-dimethyl-o-phenyl-ene)bis-(nitrilo-methanylyl-idene)]diphenol.

ABSTRACT: The asymmetric unit of the title compound, C(24)H(24)N(2)O(4), comprises two crystallographically independent mol-ecules A and B. The dihedral angles between the central dimethyl-substituted benzene ring and the two outer benzene rings are 49.5?(1) and 5.06?(11)° in mol-ecule A, and 42.55?(8) and 5.77?(9)° in mol-ecule B. In each mol-ecule, two strong intra-molecular O-H?N hydrogen bonds generate two S(6) ring motifs. The crystal structure is further stabilized by inter-molecular ?-? [centroid-centroid distances of 3.591?(1)-3.876?(1)?Å] inter-actions.

Project description:In the title compound, C(25)H(26)N(2)O(4)·CHCl(3), the aromatic rings of the imino-methyl-6-meth-oxy-phenol fragments make dihedral angles of 58.33?(6) and 87.74?(6)° with the central benzene ring.

6,6'-Dimeth-oxy-2,2'-[4,5-dimethyl-o-phenyl-enebis(nitrilo-methyl-idyne)]diphenol monohydrate.

Project description:In the title compound, C(24)H(24)N(2)O(4)·H(2)O, the dihedral angles between the central benzene ring and the two outer benzene rings of the Schiff base are 65.06?(9) and 3.02?(9)°. Strong intra-molecular O-H?N hydrogen bonds generate S(6) ring motifs. The H atoms of the water mol-ecule act as donors in the formation of bifurcated O-H?(O,O) inter-molecular hydrogen bonds with the O atoms of the hydr-oxy and meth-oxy groups with R(1) (2)(5) ring motifs; these may influence the mol-ecular conformation.

Project description:The asymmetric unit of the title compound, [Cu(C(21)H(24)N(2)O(4))]·H(2)O, comprises half of a Schiff base complex and a water mol-ecule.

The dihedral angle between the symmetry-related benzene rings is 42.56?(19)°. In the crystal, O-H?O hydrogen bonds involving the water mol-ecule make an R(2) (1)(6) ring motif. Complex mol-ecules are linked into a chain along the c axis via C-H?O inter-actions.

6,6'-Dimeth-oxy-2,2'-[2,2-dimethyl-propane-1,3-diylbis(nitrilo-methyl-idyne)]diphenol.

Project description:The title Schiff base compound, C(21)H(26)N(2)O(4), exhibits two crystallographically independent mol-ecules in the asymmetric unit with similar conformations. The imino groups are coplanar with the benzene rings; the maximum deviations of the N atoms from the planes comprising the benzene rings and the imino groups are -0.037 (4), 0.013 (4), -0.021 (5), and 0.008 (5) Å. The dihedral angles between the benzene rings in the two mol-ecules are 53.64 (17) and 51.93 (17)°. Strong intra-molecular O-H⋯N hydrogen bonds generate S(6) ring motifs. The N atoms are also in close proximity to the H atoms of the dimethyl-propane groups, with H⋯N distances between 2.54 and 2.75 Å. The crystal structure is further stabilized by weak inter-molecular C-H⋯O hydrogen bonds, weak inter-molecular C-H⋯π inter-actions and π-π contacts involving the imine C atom and two C atoms from the adjacent benzene rings.

Project description:The asymmetric unit of the title Schiff base compound, C(21)H(26)N(2)O(4), consists of four crystallographically independent mol-ecules, viz. A, B, C and D. The A and D, and the B and C mol-ecules are related by a pseudo-inversion centre, and the remaining pairs of mol-ecules differ in the orientations of one of the meth-oxy groups. In each independent mol-ecule, intra-molecular O-H⋯N hydrogen bonds generate two S(6) ring motifs. The dihedral angles between the benzene rings in mol-ecules A, B, C and D are 65.86 (19), 50.41 (19), 68.59 (19) and 50.85 (19)°, respectively. In the crystal structure, mol-ecules are linked by C-H⋯O hydrogen bonds, forming R(2) (2)(8) dimers. In addition, weak C-H⋯π inter-actions are observed.
