4,4'-Dichloro-2,2'-[2,2-dimethyl-propane-1,3-diylbis(nitrilo-methyl-idyne)]diphenol.

ABSTRACT: The crystal of the title Schiff base compound, C(19)H(20)Cl(2)N(2)O(2), contains of two crystallographically independent mol-ecules with similar conformations. In each mol-ecule, two intramolecular O-H⋯N bonds generate S(6) motifs. The N atoms are also in close proximity to two H atoms of the dimethyl-propane groups, with H⋯N distances between 2.59 and 2.62 Å. The imine group is coplanar with the benzene ring. The dihedral angles between the benzene rings in the two independent mol-ecules are 58.20 (12) and 47.95 (12)°. The structure displays short inter-molecular Cl⋯Cl [3.3869 (11) Å] and Cl⋯O [3.175 (2)-3.204 (2) Å] inter-actions. The crystal structure is further stabilized by weak inter-molecular C-H⋯O, C-H⋯π and π-π [centroid-centroid distances 3.6416 (13)-3.8705 (14) Å] inter-actions.

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.

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