Bis(5-methyl-pyrazine-2-carboxyl-ato)-diphenyl-tin(IV).

ABSTRACT: In the mol-ecule of the title compound, [Sn(C(6)H(5))(2)(C(6)H(5)N(2)O(2))(2)], two O and one N atoms from the two 5-methyl-pyrazine-2-carboxyl-ate ligands and one C atom of a phenyl group form a distorted square-planar arrangement in the equatorial plane around the Sn atom, while the distorted octa-hedral coordination is completed by an N atom of one of the 5-methyl-pyrazine-2-carboxyl-ate ligands and a C atom of the other phenyl group in the axial positions. In the crystal structure, inter-molecular C-H?O hydrogen bonds link the mol-ecules into centrosymmetric dimers.

Project description:In the title compound, [Sn(CH(3))(2)(C(5)H(3)N(2)O(2))(2)], the Sn(IV) atom is twice N,O-chelated by two pyrazine-2-carboxyl-ate ligands. The distorted six-coordination is completed by two tin-bound methyl C atoms. The C(2)N(2)O(2) donor set defines a skewed trapezoidal-bipyramidal geometry. Inter-molecular ?-? inter-actions between the pyrazine rings [centroid-centroid distance = 3.8112?(13)?Å] are observed.

Monoclinic modification of aquadi-n-butyl-bis-(pyrazine-2-carboxyl-ato-κN,O)tin(IV).

Project description:The asymmetric unit of the title organotin(IV) compound, [Sn(C(4)H(9))(2)(C(5)H(3)N(2)O(2))(2)(H(2)O)], contains one-and-a-half mol-ecules. The half-mol-ecule is completed by crystallographic twofold symmetry, with its Sn and water O atoms lying on the rotation axis. Both mol-ecules feature seven-coordinate Sn atoms in trans-C(2)SnN(2)O(3) penta-gonal-bipyramidal coordination environments. The carboxyl-ate anions N,O-chelate to the Sn atom. In the crystal, the carboxyl-ate O atoms not involved in coordination serve as acceptors for O-H⋯O hydrogen bonds from adjacent water mol-ecules, generating a three-dimensional network.

Project description:In the title compound, [Cd(C(6)H(5)N(2)O(2))(2)(H(2)O)(2)], the Cd(II) ion is coordinated in a severely distorted octa-hedral geometry. The N atoms are cis to each other, while the water O atoms and ligand O atoms are mutually trans. The crystal structure is stabilized by a network of O-H?O, O-H?N and C-H?O hydrogen bonds and ?-? stacking inter-actions [centroid-centroid distances = 3.730?(3) and 3.652?(3)?Å] between the 5-methyl-pyrazine-2-carboxyl-ate ligands. The structure is isotypic with the manganese analog.

In the crystal, the complex and uncoordinated water mol-ecules are linked by O-H⋯O, O-H⋯N and C-H⋯O hydrogen bonds, forming a three-dimensional network.

Project description:In the title complex, [Co(C(6)H(5)N(2)O(2))(2)(H(2)O)(2)]·2H(2)O, the coordination geometry of the Co(2+) cation is distorted octa-hedral, with two N atoms and two O atoms from two 5-methyl-pyrazine-2-carboxyl-ate ligands in the equatorial plane. The two remaining coordination sites are occupied by two water mol-ecules. In addition, there are two uncoordinated water mol-ecules in the asymmetric unit. The crystal structure is stabilized by a network of O-H?O and O-H?N hydrogen-bonding inter-actions, forming a three-dimensional structure.

Poly[di-?(2)-aqua-?(2)-(5-methyl-pyrazine-2-carboxyl-ato)-(5-methyl-pyrazine-2-carboxyl-ato)-?(3)-nitrato-trilithium].

Project description:The asymmetric unit of the title compound, [Li(3)(C(6)H(5)N(2)O(2))(2)(NO(3))(H(2)O)(2)](n) contains three Li(I) ions, two ligand anions, two water mol-ecules and a nitrate anion. Related by a centre of inversion, they form a centrosymmetric mol-ecular cluster in which one of the Li(I) ions shows trigonal-bipyramidal and the other two distorted tetra-hedral coordination. Li(I) ions are bridged by water O atoms and carboxyl-ate O atoms donated by one of the ligands. The clusters, bridged by two nitrato O atoms, form mol-ecular columns along [010], which are held together by O-H?O and O-H?N hydrogen bonds and ?-? inter-actions [centroid-centroid distances = 3.694?(1) and 3.796?(1)?Å].
