N,N'-Bis(6-methyl-2-pyrid-yl)oxamide.

ABSTRACT: In the crystal structure of the title compound, C(14)H(14)N(4)O(2), the mol-ecules are almost planar (mean deviation 0.028 Å) and a weak intra-molecular N-H⋯O hydrogen bond between the H atom bound to an oxamide N atom and a carbonyl O atom is found. The asymmetric unit consits of one half-mol-ecule which is located on a centre of inversion.

A triclinic polymorph with Z = 3 of N,N'-bis-(2-pyrid-yl)oxamide.

Project description:The asymmetric unit of the title compound, C(12)H(10)N(4)O(2), contains three half-mol-ecules. Each half-mol-ecule is completed by crystallographic inversion symmetry. The title compound, (I), is a polymorph of the structure, (II), reported by Hsu & Chen [Eur. J. Inorg. Chem. (2004), 1488-1493]. In the original report, the compound crystallized in the tetra-gonal space group P[Formula: see text]2(1)c (Z = 8), whereas the structure reported here is triclinic (P[Formula: see text], Z = 3). In both forms, each oxamide mol-ecule is almost planar (with maximum deviations are 0.266 and 0.166?Å) and the O atoms are trans oriented. The principal difference between the two forms lies in the different hydrogen-bonding patterns. In (I), two N-H?O and one N-H?N hydrogen bonds link the mol-ecules, forming a two-dimensional network, whereas in (II) there are no classical hydrogen bonds to O atoms and only weak C-H?O inter-actions are found along with rings of N-H?N bonds.

1,3-Bis[(6-methyl-2-pyrid-yl)meth-yl]imidazolium bromide.

Project description:The title compound, C(17)H(19)N(4) (+)·Br(-), is built up from 1,3-bis-[(6-methyl-2-pyridin-yl)meth-yl]imidazolium cations and bromide anions. Each of two 6-methyl-2-pyridyl rings is rotated out of the imidazole plane, making dihedral angles of 79.90?(9) and 86.40?(9)°. The packing is consolidated by aromatic ?-? inter-actions between the pyridine rings of neighbouring mol-ecules [centroid-centroid distance = 3.554?(2)?Å] and by weak C-H?N and C-H?Br hydrogen bonds.

N,N-Bis(6-methyl-2-pyrid-yl)formamidine.

Project description:In the crystal structure of the title mol-ecule, C(13)H(14)N(4), the two pyridyl rings are not coplanar but twisted about the C-N bond with an inter-planar angle of 71.1 (1)°. In the crystal, the mol-ecules form dimers, situated on crystallographic centres of inversion, which are connected via a pair of N-H⋯N hydrogen bonds. C-H⋯π-electron ring inter-actions are also present in the crystal structure. The title mol-ecule adopts an s-cis-anti-s-cis conformation in the solid state.

Crystal structure of N,N'-bis-(4-methyl-phen-yl)di-thio-oxamide.

Project description:Two half mol-ecules of the title compound, C16H16N2S2, are present in the asymmetric unit and both mol-ecules are completed by crystallographic inversion centers at the mid-points of the central C-C bonds: the lengths of these bonds [1.538?(5) and 1.533?(5)?Å] indicate negligible electronic delocalization. The trans-di-thio-oxamide fragment in each mol-ecule is characterized by a pair of intra-molecular N-H?S hydrogen bonds. In the crystal, mol-ecules are linked by weak C-H..? inter-actions, generating a three-dimensional network.

[Oxalylbis(aza-nedi-yl)]bis-{[amino-(2-pyrid-yl)methyl-ene]ammonium}.

Project description:The title compound, C(14)H(16)N(8)O(2) (2+)·2ClO(4) (-), was prepared by reaction of bis-[amino-(2-pyrid-yl)methyl-ene]oxalohydrazide with perchloric acid. The mol-ecular symmetry is C(i) and thus the asymmetric unit comprises one half-mol-ecule. The dihedral angle between the aromatic ring and the plane of the oxamide group is 70.8 (3)°. The perchlorate anions and the cations are connected by inter-molecular N-H⋯O hydrogen bonds.

N,N'-Bis(pyridin-3-yl)oxamide.

Project description:The title mol-ecule, C12H10N4O2, located about an inversion centre, is roughly planar, with an r.m.s. deviation from the least-squares plane of all non-H atoms of 0.019 Å. In the crystal, N-H⋯N hydrogen bonds between the amide N-H group and the pyridine N atom connect the mol-ecules into a corrugated layer parallel to (10-1).

Project description:In the title mol-ecule, C(17)H(12)N(6), the 2-pyridyl rings in the 3- and 4-positions and the 3-pyridyl ring in the 5-position make dihedral angles of 29.78?(16), 67.06?(16) and 32.97?(16)°, respectively, with the triazole group.

In the crystal, C-H?? and ?-? inter-actions [centroid-centroid distance = 3.6248?(19)?Å] link the mol-ecules, forming a two-dimensional network.

Di-?-perchlorato-bis-{?-2-[(2-pyrid-yl)methyl-amino-meth-yl]phenolato)dicopper(II) acetonitrile disolvate.

Project description:In the crystal of the dinuclear title compound, [Cu(2)(C(13)H(13)N(2)O)(2)(ClO(4))(2)]·2CH(3)CN, the two bridging perchlorate ions chelate to the two Cu(II) atoms in a ?-O:O' fashion on opposite sides of the equatorial plane. The Cu(II) ions display a distorted octa-hedral coordination geometry (in the usual 4 + 2 Jahn-Teller arrangement), each being coordinated by two O atoms from the two perchlorate ligands, and two N and O atoms from the reduced Schiff base ligand. The asymmetric unit contains two acetonitrile solvent mol-ecules. In the crystal structure, in addition to N-H?O hydrogen bonds, there are weak C-H?O inter-actions between the perchlorate O atoms and the reduced Schiff base ligand. C-H?N inter-actions are also present.
