Dichloridobis(pyrazine-2-carboxamide-?N(4))zinc(II).

ABSTRACT: In the crystal of the title compound, [ZnCl(2)(C(5)H(5)N(3)O)(2)], the mol-ecule has m symmetry, with the Zn(II) cation and Cl(-) anions located on the mirror plane. The Zn(II) cation is coordinated by two Cl(-) anions and two pyrazine-2-carboxamide ligands in a distorted ZnCl(2)N(2) tetra-hedral geometry. The two pyrazine rings are nearly perpendicular to each other [dihedral angle = 86.61?(10)°]. Inter-molecular N-H?O and N-H?N hydrogen bonds and weak C-H?O inter-actions stabilize the crystal packing.

Dichloridobis[2-(1-hydrazinylideneeth-yl)pyrazine-?N(1)]zinc.

Project description:In the structure of the title complex, [ZnCl(2)(C(6)H(8)N(4))(2)], the Zn(II) atom has a distorted octa-hedral geometry. Two cis Cl(-) ions and four N atoms belonging to two different 2-(1-hydrazinylideneeth-yl)pyrazine ligands coordinate the Zn(II) atom, forming two five-membered Zn-N-C-C-N rings. The dihedral angle between the planes of these metallocycles is 88.13?(4)°. The organic ligands are essentially planar (r.m.s. deviations from planarity = 0.072 and 0.040?Å). Inter-molecular N-H?N and N-H?Cl inter-actions join the mol-ecules into a three-dimensional framework.

Dichloridobis(isoquinoline-?N)zinc(II).

Project description:In the title compound, [ZnCl(2)(C(9)H(7)N)(2)], the Zn(II) cation is coordinated by two Cl(-) anions and two isoquinoline ligands in a distorted ZnCl(2)N(2) tetra-hedral geometry; the two isoquinoline ring systems are twisted with respect to each other at a dihedral angle of 45.72?(8)°. The parallel isoqiunoline ring systems of adjacent mol-ecules are partially overlapped, with the shorter face-to-face distance of 3.438?(19)?Å indicating the existence of weak ?-? stacking in the crystal structure.

Dibromidobis(pyrazine-2-carboxamide-?N(4))zinc.

Project description:The title complex, [ZnBr(2)(C(5)H(5)N(3)O)(2)], shows crystallographic mirror symmetry with the Zn atom and the two bromine ligands located on the mirror plane. The Zn atom is four-coordinated in a distorted tetra-hedral fashion by two N atoms from two pyrazine-2-carboxamide ligands and two Br atoms. Only one of the amino H atoms is involved in an N-H?O hydrogen bond. The crystal packing is further stabilized by weak N-H?N and C-H?O inter-actions.

Dichloridobis(phenanthridine-?N)zinc(II).

Project description:In the mol-ecule of the title compound, [ZnCl(2)(C(13)H(9)N)(2)], the Zn(II) atom is four-coordinated in a distorted tetra-hedral configuration by two N atoms from two phenanthridine ligands and by two terminal Cl atoms. The dihedral angle between the planes of the phenanthridine ring systems is 69.92?(3)°. An intra-molecular C-H?Cl inter-action results in the formation of a planar five-membered ring, which is oriented at a dihedral angle of 8.32?(3)° with respect to the adjacent phenanthridine ring system. In the crystal structure, ?-? contacts between the phenanthridine systems [centroid-centroid distances = 3.839?(2), 3.617?(1) and 3.682?(1)?Å] may stabilize the structure. Two weak C-H?? inter-actions are also found.

catena-Poly[[[aqua-(pyrazine-2-carboxamide-?(2)N(1),O)zinc]-?-pyrazine-2-carboxamide-?(3)N(1),O:N(4)] dinitrate].

Project description:In the crystal of the title compound, {[Zn(C(5)H(5)N(3)O)(2)(H(2)O)](NO(3))(2)}(n), the Zn(II) cation is N,O-chelated by two pyrazine-2-carboxamide (PCA) ligands and is further coordinated by one water mol-ecule and by one pyrazine-N atom from an adjacent PCA ligand in a distorted ZnN(3)O(3) octa-hedral geometry. One of the two independent PCA ligands bridges two Zn(II) cations, forming a zigzag polymeric chain running along the c axis. In the crystal, the NO(3) (-) anions link to the chain via O-H?O and N-H?O hydrogen bonding. Weak inter-molecular C-H?O inter-actions also occur.

Project description:In the crystal of the title polymeric compound, [Cu(2)(SO(4))(2)(C(5)H(5)N(3)O)(2)(H(2)O)(4)](n), two independent Cu(II) atoms are located on individual inversion centers.

The pyrazine-2-carboxamide ligands bridge the Cu(II) atoms to form a polymeric chain running along [110]. The crystal structure features N-H?O, O-H?O and weak C-H?O hydrogen bonds.

Dichloridobis(2-phenyl-pyridine-?N)zinc(II).

Project description:In the title compound, [ZnCl(2)(C(11)H(9)N)(2)], the Zn(2+) cation lies on a twofold axis and is coordinated by two Cl(-) anions and the N atoms of two 2-phenyl-pyridine ligands, forming a ZnN(2)Cl(2) polyhedron with a slightly distorted tetra-hedral coordination geometry. The dihedral angle between the phenyl ring and the metal-bound pyridine ring is 50.3?(4)° for each 2-phenyl-pyridine ligand. This arranges the phenyl ring from one ligand in the complex above the pyridine ring of the other resulting in an intra-molecular ?-? inter-action, with a centroid-centroid distance of 3.6796?(17)?Å. Weak C-H?Cl hydrogen bonds stabilize the crystal packing, linking mol-ecules into chains along the c axis.

Dichloridobis(5-heptyl-1,3,4-thia-diazol-2-amine-?N)zinc(II).

Project description:In the title compound, [ZnCl(2)(C(9)H(17)N(3)S)(2)], the Zn(II) atom is four-coordinated by two N atoms from two 5-heptyl-1,3,4-thia-diazol-2-amine ligands and two Cl atoms in a distorted tetra-hedral geometry. The thia-diazole rings are oriented at a dihedral angle of 84.87?(4)°. Intra-molecular N-H?Cl inter-actions result in the formation of two six-membered rings having envelope and planar conformations. In the crystal structure, inter-molecular N-H?N and N-H?Cl inter-actions link the mol-ecules into a three-dimensional network. ?-? contacts between thia-diazole rings [centroid-centroid distance = 3.602?(1)?Å] may further stabilize the structure.

Project description:In the title compound, [Cd(NO(3))(2)(C(5)H(5)N(3)O)(2)(H(2)O)(2)]·2C(5)H(5)N(3)O, the Cd(II) cation is located on a twofold rotation axis and is coordinated by two pyrazine-2-carboxamide ligands and two water mol-ecules and chelated by two nitrate anions in a distorted square-anti-prismatic geometry. Extensive inter-molecular N-H?O, N-H?N, O-H?O and O-H?N hydrogen bonds, as well as weak inter-molecular C-H?N and C-H?O inter-actions occur in the crystal. ?-? stacking between between pyrazine rings of coordinating ligands and lattice molecules [centroid-centroid distance = 3.5669?(14)?Å] may further stabilize the structure.

Dichloridobis(5-m-tolyl-1,3,4-thia-diazol-2-ylamine-κN)zinc(II).

Project description:In the mol-ecule of the title compound, [ZnCl(2)(C(9)H(9)N(3)S)(2)], the Zn(II) atom is four-coordinated by two N atoms from two 5-m-tolyl-1,3,4-thia-diazol-2-ylamine ligands and two Cl anions in a distorted tetra-hedral geometry. Intra-molecular N-H⋯N, N-H⋯Cl and C-H⋯S hydrogen bonds result in the formation of one planar and one non-planar five-membered, one non-planar six-membered and one non-planar seven-membered ring. The six- and seven-membered rings have twist conformations, while the non-planar five-membered ring adopts an envelope conformation with the S atom displaced by 0.541 (3) Å from the plane of the other ring atoms. The planar five-membered ring is oriented at dihedral angles of 1.74 (3) and 1.08 (3)°, respectively, with respect to the adjacent aromatic and thia-diazole rings. In the crystal structure, inter-molecular N-H⋯Cl hydrogen bonds link the mol-ecules into a three-dimensional network.
