چکیده
In the title complex, [La(C(6)H(4)NO(3))(C(2)O(4))(H(2)O)(2)](n), the La(III) ion is coordinated by eight O atoms from two 2-oxido-pyridinium-3-carboxyl-ate ligands, two oxalate ligands and two water mol-ecules in a distorted bicapped square-anti-prismatic geometry. The carboxyl-ate groups link adjacent La(III) ions, forming two-dimensional layers that are further linked by N-H⋯O and O-H⋯O hydrogen bonds.

The water-coordinated La(III) atom in the title compound, {[La(C(5)H(4)N(3)O(2))(C(2)O(4))(H(2)O)(2)]·H(2)O}(n), is N,O-chelated by a 3-amino-pyrazine-2-carboxyl-ate ion; this ion links adjacent metal atoms to form a chain parallel to [010]. The oxalate ion serves as a bis-bidentate chelate that links adjacent metal atoms to form a chain parallel to [001]. The two bridging ions give rise to a l...

The centrosymmetric binuclear title complex, [Mn(2)(C(8)H(5)NO(5))(2)(C(12)H(8)N(2))(2)(H(2)O)(4)]·2H(2)O, was obtained by the reaction of manganese chloride with 5-carb-oxy-1-carboxy-methyl-2-oxidopyridinium and 1,10-phenanthroline. The Mn(II) atom is coordinated by two N atoms from the 1,10-phenanthroline ligand, two O atoms from two 5-carboxyl-ato-1-carboxyl-atomethyl-2-oxidopyridinium ligan...

In the title coordination polymer, [Mn(C(8)H(5)NO(5))(H(2)O)(4)](n), the Mn(II) atom is coordinated by two carboxyl-ate O atoms from two 5-carboxyl-ato-1-carboxyl-atomethyl-2-oxidopyridinium (L(2-)) ligands and by four water mol-ecules in a distorted octa-hedral geometry. The L(2-) ligands bridge the Mn atoms into an infinite chain motif along [100]; the chains are further inter-linked by O-H⋯O...
