Dimethyl-bis-(pyrazine-2-carboxyl-ato-?(2)N(1),O)tin(IV).

ABSTRACT: 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.

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 π-π inter-actions between the pyrazine rings [centroid-centroid distance = 3.8112 (13) Å] are observed. ...[more]

Project description: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.

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.

Bis(4,6-dimethyl-pyrimidine-2-thiol-ato)dimethyl-tin(IV).

Project description:The asymmetric unit of the title complex, [Sn(CH(3))(2)(C(6)H(7)N(2)S)(2)], contains two independent mol-ecules with similar configurations. In each, the Sn(IV) cation is coordinated by two methyl and two 4,6-dimethyl-pyrimidine-2-thiol-ate anions in a distorted SnS(2)C(2) tetra-hedral geometry. In the two mol-ecules, the S-Sn-S bond angles are 87.70 (5) and 88.93 (4)°, while the C-Sn-C bond angles are 125.7 (3) and 125.9 (2)°. Weak C-H⋯N hydrogen bonding is present in the crystal structure.

Project description:In the title compound, [Sn(CH(3))(2)(C(3)H(3)N(2)S(3))(2)], the Sn(IV) atom is coordinated within a C(2)N(2)S(2) donor set that defines a skew-trapezoidal bipyramidal geometry in which the methyl groups lie over the weakly coordinated N atoms.

Project description:The asymmetric unit of the polymeric title compound, {[Pr(2)(C(5)H(4)N(3)O(2))(5)(CHO(2))(H(2)O)(5)]·6H(2)O}(n), has two independent Pr(III) atoms; one is coordinated by two water mol-ecules and the other by three water mol-ecules. The first is N,O-chelated by three 3-amino-pyrazine-2-carboxyl-ate ions, whereas the second is chelated by two carboxyl-ate ions; both exist in a monocapped square-anti-prismatic geometry. The polymeric chains that run along the a axis inter-act with the lattice water mol-ecules, generating a three-dimensional hydrogen-bonded network. The formate ion is disordered over two positions with respect to the non-coordinated atoms in a 1:1 ratio.

Poly[[hepta-μ(2)-aqua-bis-(μ(2)-pyrazine-2-carboxyl-ato)dibarium] bis-(pyrazine-2-carboxyl-ate)].

Project description:In the layered title coordination polymer, {[Ba(2)(C(5)H(3)N(2)O(2))(2)(H(2)O)(7)](C(5)H(3)N(2)O(2))(2)}(n), the coordination geometries around the two independent Ba(II) ions can be described as bicapped square-anti-prismatic [BaNO(9)] arrangements. A two-dimensional polymeric framework with (6,3) topology can be observed in the ac plane, the nodes being provided by Ba(II) ions and the connectors being N and O atoms belonging to pyrazine-2-carboxyl-ate ligands and O atoms of bridging water mol-ecules. Non-coordinating pyrazine-2-carboxyl-ate ions are located between the polymeric layers in the crystal and are interconnected through extensive O-H⋯N,O hydrogen bonding.
