cis-Diaqua-bis-[dimethyl (phenyl-sulfonyl-imino)-phospho-nato]cobalt(II).

In the title diaquacobalt complex, [Co(C8H11NO5PS)2(H2O)2], the CoII atom is surrounded by six O atoms belonging to the phosphoryl and sulfonyl groups of two deprotonated chelate ligands and two additional O atoms from water molecules which are in cis positions with respect to one another. The coordination environment of cobalt can be described as a distorted octahedron. O—H⋯O hydrogen bonds between the water and sulfonyl O atoms of neighboring molecules form chains running parallel to [010]. Two methoxy groups attached to one phosphorus are disordered over two sets of sites in a 0.6:0.4 ratio.

catena-Poly[calcium-bis­[μ-N-(dimethyl­phosphino­yl)benzene­sulfonamidato]]

The crystal structure of the title calcium complex, [Ca(C8H11NO5PS)2]n, is composed of a polymeric chain, which is formed due to two bridging sulfonyl groups linking CaII ions in a O—S—O—Ca manner. Thus, the coordination environment of the CaII ions is composed of six O atoms belonging to the phosphoryl and sulfonyl groups of two chelate rings and two additional O atoms of two bridging sulfonyl groups. The coordination polyhedron of the central atom (2 symmetry) has a distorted octahedral geometry.

Nanodimension thin films based on lanthanide coordination compound for light-emitting devices

Samples of planar light-emitting heterostructures based on thin films of polyfluorine PFD and europium carbacylamidophosphate complexes blends (ITO/PEDOT:PSS/PFD/Ca+Al and ITO/PEDOT:PSS/PFD+Complex/Al+Ca; Complex = EuWi3Phen or EuWi3KM) have been prepered. The obtained films were characterized by means of atomic force microscopy and fluorescence spectroscopy. The electric response of the devices wasevaluated based on the I-V characteristics.
