1,1'-[o-Phenyl-enebis(nitrilo-methyl-idyne)]di-2-naphthol ethanol hemisolvate.

ABSTRACT: The asymmetric unit of the title compound, C(28)H(20)N(2)O(2)·0.5C(2)H(5)OH, contains two independent mol-ecules of 1,1'-[o-phenyl-enebis(nitrilo-methyl-idyne)]di-2-naphthol, denoted A and B, and one ethanol solvent mol-ecule. The hydr-oxy groups are involved in intra-molecular O-H?N hydrogen bonds influencing the mol-ecular conformations, which are slightly different in mol-ecules A and B, where the two bicyclic systems form dihedral angles of 51.93?(9) and 58.52?(9)°, respectively. In the crystal structure, a number of short inter-molecular C?C contacts with distances of less than 3.5?Å suggest the existence of ?-? inter-actions, which contribute to the stability of the crystal packing.

Project description:The title compound, [Co(C(20)H(14)N(2)O(2))(C(5)H(5)N)(2)]ClO(4) or [Co(salophen)(py)(2)]ClO(4), where salophen is o-phenyl-enebis(nitrilo-methyl-idyne)]diphenolate and py is pyridine, contains a six-coordinate mononuclear cobalt(III) atom. The two phenolic O atoms and the two imine N atoms are located in cis positions. There are two pyridine mol-ecules attached to the metal atom, filling the axial sites with a mutually perpendicular disposition of the pyridine planes [86.11?(5)°]. The Co complexes are stacked in layers parallel to (100). Coherence of the structure is provided by a variety of C-H?O interactions between the complexes and the perchlor-ate counter anion.

{1,1'-[(2,2-Dimethyl-propane-1,3-di-yl)bis-(nitrilo-methyl-idyne)]di-2-naphthol-ato}dioxidomolybdenum(VI) dichloro-methane 1.75-solvate.

Project description:In the crystal structure of the title compound, [Mo(C(27)H(24)N(2)O(2))O(2)]·1.75CH(2)Cl(2), the Mo(VI) ion is coordinated by two oxide O atoms and by two O and two N atoms of the tetra-dentate 1,1'-[(2,2-dimethyl-propane-1,3-di-yl)bis-(nitrilo-methyl-idyne)]di-2-naphtholate Schiff base ligand in a distorted octa-hedral configuration. The compound crystallizes with 1.75 mol-ecules of dichloro-methane per complex mol-ecule. In the crystal, symmetry-related mol-ecules are linked by a number of C-H⋯O inter-actions involving both the Schiff base ligand and the partly disordered dichloro-methane solvent mol-ecules, leading to the formation of a two-dimensional network extending parallel to (101).

6,6'-Dieth-oxy-2,2'-[4,5-dimethyl-o-phenyl-enebis(nitrilo-methyl-idyne)]diphenol-ethanol-water (1/1/1).

Project description:The title bis-Schiff base compound, C(26)H(28)N(2)O(4)·C(2)H(6)O·H(2)O, crystallizes as an ethanol and water solvate. Strong intra-molecular O-H⋯N hydrogen bonds generate S(6) ring motifs. The water H atoms form bifurcated O-H⋯(O,O) inter-molecular hydrogen bonds with the O atoms of the hydroxyl and eth-oxy groups with R(1) (2)(5) ring motifs, which may, in part, influence the mol-ecular configuration. The dihedral angles between the central benzene ring and the two outer benzene rings of the Schiff base mol-ecule are 5.64 (8) and 44.78 (9)°. The crystal structure is further stabilized by inter-molecular C-H⋯O and π-π inter-actions [centroid-centroid distances = 3.6139 (11)-3.7993 (11) Å].

Project description:The asymmetric unit of the title complex, [Mn(C(28)H(30)N(2)O(2))Cl(H(2)O)][Mn(C(28)H(30)N(2)O(2))Cl(CH(3)OH)], contains two discrete Mn(III) complexes of a Schiff base ligand, with an N(2)O(2) donor set. Both Mn(III) centers are in a distorted octa-hedral geometry with the N(2)O(2) donor atoms of the tetra-dentate Schiff base dianion in the equatorial plane. The axial positions in the coordination environment of one Mn(III) complex are occupied by a chloride ion and a water mol-ecule, but a methanol mol-ecule replaces the water mol-ecule in the other complex. The coordinated water mol-ecule takes part in an O-H⋯Cl hydrogen bond between the two Mn(III) complexes. In the crystal structure, O-H⋯Cl hydrogen bonds link the mol-ecules into infinite one-dimensional chains along the [100] direction. The crystal structure is stabilized by O-H⋯Cl hydrogen bonds together with weak C-H⋯O and C-H⋯Cl inter-actions. A C-H⋯π inter-action is also observed in the crystal structure.

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.
