6,6'-Diethoxy-2,2'-[2,2-dimethylpropane-1,3-diylbis(nitrilomethylidyne)]diphenol.

ABSTRACT: In the crystal structure, the title Schiff base compound, C(23)H(30)N(2)O(4), exhibits crystallographic twofold rotation symmetry. The imino group is coplanar with the aromatic ring with an N-C-C-C torsion angle of -179.72 (9)°. An intra-molecular O-H⋯N hydrogen bond forms a six-membered ring, producing an S(6) ring motif. The dihedral angle between symmetry related benzene rings is 28.05 (5)°. The eth-oxy group makes a C-O-C-C torsion angle of -7.20 (16)° with the benzene ring. The crystal structure is stabilized by inter-molecular C-H⋯π inter-actions.

Dioxido{4,4',6,6'-tetrabromo-2,2'-[2,2-dimethylpropane-1,3-diylbis(nitrilomethanylylidene)]diphenolato}molyb-denum(VI).

Project description:The asymmetric unit of the title compound, [Mo(C(19)H(16)Br(4)N(2)O(2))O(2)], comprises two mol-ecules. The coordination environments around the Mo(VI) atoms are distorted octa-hedral, defined by two oxide ligands and an N(2)O(2) donor set of the tetra-dentate Schiff base in each mol-ecule. The dihedral angles between the benzene rings in the mol-ecules are 76.2 (3) and 77.7 (3)°. An inter-esting feature of the crystal structure is the presence of Br⋯Br contacts [3.4407 (11), 3.5430 (11) and 3.6492 (10) Å], which are shorter than the sum of the van der Waals radius of Br atoms (3.70 Å). The crystal structure is further stabilized by inter-molcular C-H⋯Br and C-H⋯π inter-actions. The crystal under investigation was twinned by nonmerohedry in a 0.053 (1):0.947 (1) ratio.

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.

{6,6'-Diethoxy-2,2'-[4,5-dimethyl-o-phenylenebis(nitrilomethylidyne)]di-phenolato}nickel(II) dihydrate.

Project description:In the title complex, [Ni(C(26)H(26)N(2)O(4))]·2H(2)O, the Ni(II) ion, lying on a twofold crystallographic rotation axis, has a square-planar geometry, being coordinated by the N(2)O(2) unit of the tetra-dentate Schiff base ligand. The asymmetric unit of the title compound comprises one-half of the complex mol-ecule and one of the water mol-ecules of crystallization. The water H atoms form bifurcated O-H⋯(O,O) hydrogen bonds with the O atoms of the phenolato and eth-oxy groups with R(1) (2)(5) and R(1) (2)(6) ring motifs. The dihedral angle between the central benzene ring and the two outer benzene rings are 4.07 (11) and 3.99 (12)°. The dihedral angle between the two O-Ni-N coordination planes is only 0.77 (11)°. In the crystal structure, the mol-ecules are linked together into extended chains along the c axis by inter-molecular O-H⋯O and C-H⋯O inter-actions. An inter-esting feature of the crystal structure is a short inter-molecular C ⋯ C [3.355 (3) Å] contact, which is shorter than the sum of the van der Waals radii. The crystal structure may be further stabilized by inter-molecular π-π inter-actions [centroid-centroid distances in the range 3.5758 (13)-3.6337 (13) Å].

Project description:In the title hexa-hydro-pyrimidine derivative, C(28)H(42)N(2)O(4)·0.19H(2)O, the 1,3-diazinane ring has a chair conformation with a diequatorial substitution.

The partially occupied water mol-ecule is also located on this mirror plane. The dihedral angle between the planes of the aromatic rings is 17.71 (3)°. Two intra-molecular O-H⋯N hydrogen bonds with graph-set motif S(6) are present. No remarkable inter-molecular contacts exist in the crystal structure.

Project description:The asymmetric unit of the title compound, [Zn(C(19)H(16)Cl(4)N(2)O(2))(H(2)O)], comprises two crystallographically independent mol-ecules. The geometry around the Zn(II) atoms is distorted trigonal-bipyramidal, supported by the N(2)O(2) donor atoms of the tetradentate Schiff base and a coordinating water mol-ecule. The dihedral angles between the benzene rings in the two mol-ecules are 34.10 (15) Å and 30.61 (15) Å. In the crystal, neighbouring independent mol-ecules are linked by pairs of O-H⋯O hydrogen bonds, forming dimers with R(2) (2)(6) ring motifs, and by O-H⋯Cl hydrogen bonds. There are short Cl⋯Cl [3.4728 (16), 3.4863 (16), and 3.388 (1) Å] contacts present, and mol-ecules are also linked by C-H⋯O and π-π [centroid-centroid distance = 3.671 (2) Å] inter-actions.
