Tetrakis(μ-N-acetyl-N-phenyl­glycinato-κ²O,O′)­bis­[(N-acetyl-N-phenyl­glycinato-κ³O,O,O)(1,10-phenanthroline-κ²N,N′)­cerium(III)] dihydrate

In the title complex, [Ce₂(C₁₀H₁₀NO₃)₆(C₁₂H₈N₂)₂]·2H₂O, each Ce atom shows a distorted tricapped trigonal prismatic coordination, comprising two N-atom donors from a 1,10-phenanthroline ligand and seven O atoms of the N-acetyl-N-phenyl­glycine (L2) mol­ecules. Two Ce atoms are bridged by two terdentate and two bidentate carboxyl­ate groups of L2, to give a centrosymmetric dimer. The crystal structure is stabilized by intermolecular O—H...O hydrogen bonds.

The uncoordinated water mol­ecule interacts with nearby carboxyl groups of the pyridine-2-carboxyl­ate ligands by way of O—H...O hydrogen bonds.

catena-Poly[tris(ethyl­enediamine-κ²N,N′)nickel(II) [cadmium(II)-di-μ-1,2-dicyano­ethyl­enedithiol­ato-κ³S,S′:S′] monohydrate]

The title compound, {[Ni(C₂H₈N₂)₃][Cd(C₄N₂S₂)₂]·H₂O}_n, contains chains of bis­(1,2-dicyano­ethyl­enedithiol­ato)­cadmate(II) complex anions, tri(ethyl­enediamine)nickel(II) cations and uncoordinated water mol­ecules. The Cd^II centre is in a very distorted CdS₆ octa­hedral environment. Three bidentate ethyl­enediamine ligands are coordinated to the Ni^II atom, resulting in somewhat distorted NiN₆ octa­hedra. The polymeric anionic chains, cations and water mol­ecules are linked by hydrogen bonds into a three-dimensional framework.

In the title compound, C₁₂H₉N₂⁺·C₇H₅O₄N⁻·C₁₂H₈N₂·C₇H₄O₄N·C₂H₆O·H₂O, the cations are stacked along the b axis to form a column-like structure. The anions, ethanol mol­ecules and water mol­ecules are linked via O—H...O and O—H...N hydrogen bonds to form a zigzag sheet-like structure. The cationic columns and anionic sheets are alternately arranged along the c axis.
