The reaction of substitution of carbon monoxide by P(OMe) 3 in the complex (µη 2 PhC(S)=C(S)Ph)Fe 2 (CO) 6 1 under thermal activation afforded two colored compounds: a binuclear disubstituted complex (µ-PhC(S)=C(S)Ph)Fe 2 (CO) 4 [P(OMe) 3 ] 2 2 and a mononuclear iron disubstituted complex (η 2 PhC(S)=C(S)Ph)Fe(CO)[P(OMe) 3 ] 2 3. Mass spectrometry, 1 H NMR, IR and electrochemical studies established that two (CO) have been substituted by P(OMe) 3 in complexes 2 and 3. The X-ray studies show that the two P(OMe) 3
In the mononuclear title complex, [Co(C10H6NO4)2(C7H10N2)2(H2O)2], the CoII ion is located on an inversion centre and has a distorted octahedral coordination geometry of type CoN2O4 by two N atoms from the two 4-(dimethylamino)pyridine (DMAP) ligands, two carboxylate O atoms from the two deprotonated N-phthaloylglycine (Nphgly) ligands [systematic name: 2-(1,3-dioxo-2,3-dihydro-1H-isoindol-2-yl)acetate] and two coordination water molecules. In the crystal, O—H...O, C—H...O hydrogen bonds and π–π stacking interactions link the molecules into the supramolecular structure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
