Poly[[aqua­(1,10-phenanthroline)lead(II)]-μ₃-3-sulfonatobenzoato]

In the title compound, [Pb(C₇H₄O₅S)(C₁₂H₈N₂)(H₂O)]_n, each Pb^II atom is coordinated by five O atoms from one water mol­ecule and three 3-sulfonatobenzoate ligands and two N atoms from one 1,10-phenanthroline. The 3-sulfonatobenzoate ligand serves as a μ₃-bridge, linking three Pb^II atoms, and extends the structure into a one-dimensional ladder. The O—H...O hydrogen bonds generate a two-dimensional layer and enhance the stability of the structure.

Aqua­bis(1,10-phenanthroline)(3-sulfonatobenzoato)cadmium(II) tetra­hydrate

In the title mononuclear complex, [Cd(C₇H₄O₅S)(C₁₂H₈N₂)₂(H₂O)]·4H₂O, the Cd^II atom is coordinated in a capped trigonal–prismatic geometry by four N atoms and three O atoms. The 3-sulfonatobenzoate ligand chelates the Cd^II atom only via the carboxyl group. In the crystal structure, extensive O—H...O hydrogen bonds generate a three-dimensional network.

cis-Diaqua­bis(1,10-phenanthroline)manganese(II) 4-sulfonatobenzoate 6.5-hydrate

In the title complex salt, [Mn(C₁₂H₈N₂)₂(H₂O)₂](C₇H₄O₅S)·6.5H₂O, the coordination geometry about the Mn^II atom is distorted octahedral, defined by four N atoms from two 1,10-phenanthroline ligands and two O atoms from two water mol­ecules. O—H...O hydrogen-bonding inter­actions among cations, anions, and solvent water mol­ecules generate a three-dimensional network and enhance the stability of the crystal structure.
