A Novel Molecular Based Ferromagnet Ordering at 14 K

The compound MnCu(obbz)*H2O , obtained by reaction of the Mn2+ ion with the copper (II) 'brick' 2-, orders ferromagnetically at Tc = 14 K; below Tc it exhibits a hysteresi

Oxalamide based coordination polymers

Employment of N,N′-bis(2-dicarboxyphenyl)-oxalamide (H4L) in the M2+ chemistry (M = Mg, Mn, Co, Ni, and Zn) afforded five 2-D coordination polymers and one 1-D coordination polymer. The crystal structures of all complexes have been d

Identification of degradation products of indigoids by tandem mass spectrometry

The study concerns identification of photodegradation products of indigotin, indirubin and isoindigo. Experimental methodology consists of degradation of standard solutions of indigoids in a solar box and analysis of samples taken at different aging time by using capillary high-performance liquid chromatography coupled with electrospray ionization tandem mass spectrometric and spectrophotometric detectors. Identification of the formed compounds was based on careful interpretation of the electrospray ionization MS/MS spectra. Apart from the well-known degradation products of indigoids: isatin, isatoic anhydride and anthranilic acid, another seven species were also identified, and their proposed structures were confirmed by high-resolution molecular masses measurements; according to the best knowledge of authors, they have not been reported so far. The obtained results formed the basis for postulating mechanism of the process. Moreover, the MRM (Multiple Reaction Monitoring) method was developed for the identification of natural dyes and their degradation products in textiles of historical value. Apart from such colorants as indigotin and flavonoids, also presence of degradation products of indigoids was confirmed.

MULTIDENTATE LIGAND, MULTI-NUCLEUS METAL COMPLEX, METAL COMPLEX CHAIN, METAL COMPLEX INTEGRATED STRUCTURE, AND PREPARATION METHOD THEREOF

An object of the present invention is typically to provide a metal complex assembly that is applicable to the miniaturization and elaboration of devices and apparatus in information and communication fields, such as arithmetic and logic units, displays and memories, and to provide a novel multidentate ligand which can be used as a suitable raw material for the metal complex assembly. The present invention is as follows. A multidentate ligand includes at least two planar tetradentate coordination sites in one plane, each of the planar tetradentate coordination sites containing four nitrogen-containing groups of at least one of imino, amido and amino groups, and has the nitrogen atoms of the four nitrogen-containing groups as coordinating atoms in one plane. A metal complex assembly has one of two-dimensional and three-dimensional structures and contains metal complex chains and electroconductive wires, the metal complex chains each contain assembled metal complexes, the electroconductive wires each contain molecules serving as at least one of an acceptor and a donor, and the metal complex chains intersect with the electroconductive wires at such positions that the metal complexes and the molecules serving as at least one of an acceptor and a donor are capable of interacting with each other.
