(-)-Dimethyl 3,3'-diphenyl-2,2'-[pyridine-2,6-diylbis(carbonyl-imino)]dipropanoate.

ABSTRACT: The title compound, C(27)H(27)N(3)O(6), a bis-amide derivative, is also a chiral amino acid ester with l-phenyl-alanine methyl ester groups as amine substituents. The pyridine ring is oriented at dihedral angles of 89.69?(3) and 62.95?(3)° with respect to the phenyl rings, while the dihedral angle between the phenyl rings is 60.76?(3)°. In the crystal structure, inter-molecular N-H?O hydrogen bonds link the mol-ecules into chains. One of the carbonyl O atoms and one of the meth-oxy CH(3) groups are disordered over two positions. The O atom was refined with occupancies of 0.69?(13) and 0.31?(13), while C and H atoms were refined with occupancies of 0.69?(8) and 0.31?(8).

Project description:In the title compound, C(21)H(21)Cl(2)NO(2), the piperidine ring adopts a distorted boat conformation. The two phenyl rings are approximately perpendicular to each other, with a dihedral angle of 86.12 (7)°. Mol-ecules are linked into centrosymmetric dimers by pairs of bifurcated C-H⋯O hydrogen bonds, forming R(2) (2)(10) and R(2) (2)(14) ring motifs, and an intramolecular C-H⋯O link also occurs.

Project description:In the asymmetric unit of the title compound, [ZnCl(2)(C(14)H(14)N(2))], the central Zn(II) ion is four-coordinated in a distorted tetra-hedral environment by two N atoms of the ligand 2-[(2,6-dimethyl-phen-yl)imino-meth-yl]pyridine and two chloride anions.

3,3'-Diphenyl-1,1'-[2,2'-oxybis(2,1-phenyl-ene)]diurea N,N-dimethyl-formamide disolvate.

Project description:In the structure of the title compound, C(26)H(22)N(4)O(3)·2C(3)H(7)NO, one of the DMF solvent mol-ecules is disordered over two sets of positions in a 0.5:0.5 ratio. In the 1,1'-[2,2'-oxybis(2,1-phenyl-ene)]bis-(3-phenyl-urea) mol-ecule, the two diphenyl-urea segments are linked via an ether O atom and are inclined at an angle of 53.80?(4)° to one another. In the crystal structure, classical N-H?O hydrogen bonds link each mol-ecule to two DMF solvent mol-ecules and these aggregates form columns down a through C-H?? inter-actions. Additional C-H?O inter-actions link the main mol-ecule and the solvent mol-ecules, forming columns of independent zigzag chains along b.

3,3'-Dimethyl-1,1'-[2,2'-bipyridine-5,5'-diylbis(methyl-ene)]diimidazol-3-ium bis-(hexa-fluoro-phosphate).

Project description:The title compound, C(20)H(22)N(6) (2+)·2PF(6) (-), was prepared by the reaction of 5,5'-bis-(bromo-meth-yl)-2,2'-bipyridine with 1-methyl-imidazole. The main mol-ecule lies on an inversion center located at the mid-point of the C-C bond joining the two pyridine rings. The asymmetric unit therefore contains one half-mol-ecule and one hexa-fluoro-phosphate anion. The dihedral angle between the pyridine and imidazole rings is 76.93 (7)°. In the crystal, weak inter-molecular C-H⋯F hydrogen bonds contribute to the stabilization of the packing.

Diaqua-tris-(nitrato-?(2)O,O'){2,2'-[pyridine-2,6-diylbis(methyl-ene-oxy)]dibenzaldehyde-?O(1)}dysprosium(III)-2,2'-[pyridine-2,6-diylbis(methyl-ene-oxy)]dibenzaldehyde (1/1).

Project description:The title compound, [Dy(NO(3))(3)(C(21)H(17)NO(4))(H(2)O)(2)]·C(21)H(17)NO(4), may be considered as an organic-metalorganic 1:1 co-crystal, in which the two dialdehyde mol-ecules act as a ligand and as an organic moiety, respectively. The Dy(III) atom coordinates nine O atoms from the organic ligand, bidentate nitrate ions and water mol-ecules, approximating a square-face-tricapped trigonal-prismatic geometry. The coordinated dialdehyde is not planar: the uncoordinated oxybenzaldehyde group is twisted by 39.96?(4)° from the rest of the ligand. In contrast, the free organic moiety is almost planar, with an r.m.s. deviation of 0.15?Å. In the crystal, segregated stacks of dialdehyde are formed in the [100] direction. For the complex, the shortest ?-? contact is found at 3.781?(2)?Å, and for the free ligand, at 3.785?(2)?Å. The crystal structure is further stabilized by O-H?O and O-H?N hydrogen bonds in which coordinated water mol-ecules are the donor groups.
