Crystal structure of a samarium(III) nitrate chain cross-linked by a bis-carbamoyl­methyl­phosphine oxide ligand

The crystal structure of the title compound consists of a polymeric chain of Sm^III cations and nitrate anions, cross-linked in two dimensions with an organic ligand.

Crystal structure of [propane-1,3-diylbis(piperidine-4,1-di­yl)]bis­[(pyridin-4-yl)methanone]–isophthalic acid (1/1)

In the co-crystal of isophthalic acid and [propane-1,3-diylbis(piperidine-4,1-di­yl)]bis­[(pyridin-4-yl)methanone], mol­ecules are connected into supra­molecular chains aligned along the c axis by O—H...N hydrogen bonding. These aggregate into supra­molecular layers oriented parallel to the ac plane by C—H...O inter­actions.

Crystal structure of penta­kis­(ethyl­enedi­amine-κ²N,N′)lanthanum(III) trichloride–ethylene­diamine–dichloromethane (1/1/1)

The crystal structure of the title compound consists of a ten-coordinate lanthanum(III) cation chelated by five ethyl­enedi­amine ligands. This complex co-crystallized with one mol­ecule of ethyl­enedi­amine and three chloride anions.
