Tetra-aqua-bis-[4-(pyrazin-2-ylsulfanylmeth-yl)benzoato]manganese(II) dihydrate.

ABSTRACT: The title compound, [Mn(C(12)H(9)N(2)O(2)S)(2)(H(2)O)(4)]·2H(2)O, has been synthesized with a flexible asymmetrical bridging ligand, 4-(pyrazin-2-ylsulfanylmeth-yl)benzoic acid (Hpztmb). The Mn(II) ion exhibits a centrosymmetric octa-hedral geometry involving two carboxyl-ate O atoms of two different pztmb ligands and four O atoms of four coordinated water mol-ecules. The packing shows a three-dimensional supra-molecular network via O-H?O and O-H?N hydrogen bonds and ?-? stacking inter-actions [centroid-centroid distances = 3.884?(8) and 4.034?(8)?Å] between the benzene ring of one pztmb anion and the pyrazine ring of an adjacent anion.

Project description:In the title compound, [Mn(C(10)H(7)N(2)O(2))(2)(H(2)O)(4)], the Mn(II) atom, lying on an inversion center, has an octa-hedral environment with four coordinated water mol-ecules in the equatorial plane and two N atoms from two 4-(imidazol-1-yl)benzoate ligands at the axial sites. The complex mol-ecules are connected into a three-dimensional network by extensive hydrogen bonds between the water mol-ecules and the carboxyl-ate O atoms.

Project description:In the title compound, [Mn(C(12)H(8)NO(2))(2)(H(2)O)(4)], the Mn(2+) ion lies on a twofold rotation axis and has a distorted N(2)O(4) octa-hedral coordination geometry formed by four water O atoms in the equatorial plane and two apical pyridyl N atoms. A three-dimensional network is formed in the crystal structure by multiple O-H?O hydrogen bonds between the coordin-ating water molecules and the free carboxylate groups.

Tetra-aqua-bis{5-[2-(1H-tetrazol-5-yl)ethenyl]pyrazolato-κN}manganese(II) dihydrate.

Project description:The title compound, [Mn(C(4)H(3)N(8))(2)(H(2)O)(4)]·2H(2)O, represents the first structurally characterized transition metal complex of the 1,2-bis-(tetra-zol-5-yl)ethene ligand. The complex mol-ecule occupies a special position on an inversion centre and the Mn atom has a tetra-gonally distorted octa-hedral coordination. The bis-(tetra-zolyl)ethene ligand is planar within 0.0366 (7) Å. All 'active' H atoms participate in hydrogen bonds, which link mol-ecules of the complex and the uncoordinated water mol-ecules into an infinite three-dimensional framework.

Project description:In the crystal structure of the title complex, {[Mn(C(11)H(14)NO(2))(2)(H(2)O)(3)]·2H(2)O}(n), the two independent Mn(II) atoms are located on a centre of symmetry and coordinated by two 4-(diethyl-amino)benzoate (DEAB) anions and two water mol-ecules in the basal plane while another water mol-ecule bridges the Mn atoms in the apical directions, forming polymeric chains. The dihedral angles between the carboxyl-ate groups and the adjacent benzene rings are 11.33?(13) and 10.90?(9)° and the benzene rings are oriented at a dihedral angle of 67.88?(6)°. The uncoordinated water mol-ecules link the carboxyl-ate groups and coordinated water mol-ecules via O-H?O hydrogen bonding. Weak C-H?? inter-actions are also found in the crystal structure.
