Synthesis and properties of rhodium(I) chloranilate and 2,5-dihydroxy-1,4-benzoquinonate complexes. Crystal structures of the binuclear [Rh2(.mu.-CA)(cod)2] and tetranuclear [Rh4(.mu.-CA)2(cod)4] complexes (CA = chloranilate anion)

Mono-, di- and tetra-nuclear p-cymeneruthenium complexes containing oxalato ligands

“…Many organorhodium complexes containing bidentate oxygen ligands such as β-diketonate, 1 tropolonate (the anion of 2-hydroxycyclohepta-2,4,6-trienone), 2 oxalate, 3 chloranilate (the dianion of 2,5-dichloro-3,6-dihydroxy-p-benzoquinone), 4 squarate (3,4-dihydroxycyclobut-3-ene-1,2-dionate), 5 pyronate and pyridinonate 6 anions are known. In contrast, organoruthenium complexes containing bidentate oxygen ligands have not been extensively studied.…”

Synthesis, Spectroscopic, and Anticancerous Properties of Mixed Ligand Palladium(II) and Silver(I) Complexes with 4,6-Diamino-5-hydroxy-2-mercaptopyrimidine and 2,2′-Bipyridyl

“…The proton of the hydroxyl group O(5)H appears as a broad singlet at δ 9.13 ppm and the N(1)H proton gives a singlet at δ 7.43 ppm. In the 1 H NMR spectrum of [Pd(bpy)(dahmp)] + , the proton of the hydroxyl group is not observed while the resonance arising from N(6)H 2 is shifted to lower field [24, 30]. Also, the resonances arising from N(4)H 2 and N(1)H are slightly shifted to lower field.…”

Alkali Salts of Nitranilic and Cyanochloranilic Acids

“…[2] They can bind to transition metal ions as terminal or bridging ligands, [2] and are able to form a wide variety of topologies, ranging from discrete complexes, [3][4][5][6][7][8] 1D and 2D coordination polymers [9][10][11][12][13][14] to porous 3D metal-organic frameworks. [15,16] A unique property of 2,5-dihydroxyquinones is their capability for face-to-face π-stacking.…”
