چکیده
The polymeric structure of the title compound, [Pb(C(5)H(3)N(2)O(2))(2)(H(2)O)](n), is built up from centrosymmetric [Pb(C(5)H(3)N(2)O(2))(2)(H(2)O)](2) dimers, which are bridged by ligand carboxyl-ate O atoms. The Pb(II) ion adopts an irregular PbN(2)O(5) coordination polyhedron; it is chelated by one N,O-bidentate ligand and also bonds to a water O atom. A second N,O-bidentate ligand forms the dimer bridge and another bridging O atom from a nearby dimer also bonds to the Pb(II) ion, leading to layers propagating in (100). A network of O-H⋯O hydrogen bonds operates between water O atoms (donors) and carboxyl-ate O atoms (acceptors).

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 title compound [Cu(2)(C(6)H(3)BrNO(2))(4)](n), forms sheets in the bc plane. The structure features the dinuclear paddle-wheel cage motif common to copper(II) carboxyl-ates. The polymeric structure is achieved through bridging between binuclear units by the pyridyl donors of two of the four carboxyl-ates of the cage. Each cage engages in axial bonding at each copper atom to a pyridyl nitro-...
