Aqua-azido-{3,3'-[o-phenyl-enebis(nitrilo-methyl-idyne)]di-2-naphtholato}manganese(III).

ABSTRACT: In the title complex, [Mn(C(28)H(18)N(2)O(2))(N(3))(H(2)O)], the Mn(III) ion adopts a distorted fac-MnO(3)N(3) octa-hedral geometry arising from the O,N,N',O'-tetra-dentate Schiff base ligand, an azide ion and a water mol-ecule. In the crystal, inter-molecular O-H?(O,O) and O-H?N hydrogen bonds and ?-? inter-actions [centroid-centroid separation = 3.5535?(13)?Å] link the mol-ecules into chains.

In the title complex, [Mn(C(28)H(18)N(2)O(2))(N(3))(H(2)O)], the Mn(III) ion adopts a distorted fac-MnO(3)N(3) octa-hedral geometry arising from the O,N,N',O'-tetra-dentate Schiff base ligand, an azide ion and a water mol-ecule. In the crystal, inter-molecular O-H⋯(O,O) and O-H⋯N hydrogen bonds and π-π inter-actions [centroid-centroid separation = 3.5535 (13) Å] link the mol-ecules into chains. ...[more]

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.

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

Project description: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 π-π inter-actions, which contribute to the stability of the crystal packing.

Project description:In the title compound, [Mn(C(20)H(14)N(2)O(2))(N(3))(H(2)O)]·0.5H(2)O, the Mn(III) ion is chelated by the N,N',O,O'-tetra-dentate Schiff base ligand and further coordinated by one azide ion and one water mol-ecule in trans positions, resulting in a distorted fac-MnN(3)O(3) octa-hedral arrangement. The O atom of the uncoordinated water mol-ecule lies on a crystallographic twofold axis. In the crystal, O-H?O and O-H?N hydrogen bonds help to establish the packing.

Project description:In the title complex, [Mn(C(22)H(18)N(2)O(2))Cl], the Mn(III) center is in a distorted square-pyramidal configuration; the basal plane is formed by the N(2)O(2) donors of the tetra-dentate Schiff base dianion, with the two phenol O atoms and two imine N atoms each mutually cis. The chloride ion occupies the apical coordination site. The dihedral angle between the two outer phenolate rings of the tetra-dentate ligand is 18.24 (9)°. The central benzene ring makes dihedral angles of 13.71 (8) and 30.50 (8)° with the two outer phenolate rings. In the crystal structure, weak C-H⋯Cl inter-actions link the mol-ecules into screw helices along the b direction. These helices are further connected by weak C-H⋯O inter-actions into a three-dimensional network. The crystal structure is further stabilized by C-H⋯π inter-actions involving the central benzene ring.

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.
