C4H6, Cobalt compounds
Cobalt(II) acetate (71-48-7, 6147-53-1, 71-48-7, 5931-89-5)
Cobalt(II) acetate is the cobalt(II) salt of acetic acid. It is commonly found as the tetrahydrate Co(C2H3O2)2·4 H2O or Co(CH3COO)2·4 H2O also abbreviated Co(OAc)2·4 H2O. It is used as an industrial catalyst.
N,N-ethylenebis(salicylideneiminato)cobalt(II) · salcomine
Salcomine is a coordination complex derived from the salen ligand and cobalt. The complex, which is planar, and a variety of its derivatives are carriers for O2 as well as oxidation catalysts.
Cobalt tetracarbonyl hydride (16842-03-8)
Cobalt tetracarbonyl hydride is an organometallic compound with the formula HCo(CO)4. It is a volatile, yellow liquid that forms a colorless vapor and has an intolerable odor. The compound readily decomposes upon melt and in absentia of high CO partial pressures forms Co2(CO)8.
Nikelocen [Czech] (1271-28-9)
Nickelocene is the organonickel compound with the formula Ni(η5-C5H5)2. Also known as bis(cyclopentadienyl)nickel or NiCp2, this bright green paramagnetic solid is of enduring academic interest, although it does not yet have any known practical applications.
Vanadyl chloride (7727-18-6)
trichlorooxo vanadium · vanadium oxychloride (VOC13)
Vanadium oxytrichloride is the inorganic compound with the formula VOCl3. This yellow distillable liquid hydrolyzes readily in air. It is an oxidant.
VANADIUM PENTOXIDE (1314-62-1)
Vanadium(V) oxide (vanadia) is the inorganic compound with the formula V2O5. Commonly known as vanadium pentoxide, it is a brown/yellow solid, although when freshly precipitated from aqueous solution, its colour is deep orange. Because of its high oxidation state, it is both an amphoteric oxide and an oxidizing agent.
Nickel sulfide (Ni3S2) (12035-72-2)
Vanadium dioxide (12036-73-6, 12036-21-4)
Vanadium(IV) dioxide is an inorganic compound with the formula VO2. It is a dark blue solid. Vanadium(IV) dioxide is amphoteric, dissolving in non-oxidising acids to give the blue vanadyl ion, [VO]2+ and in alkali to give the brown [V4O9]2− ion, or at high pH [VO4]4−.
Vanadium chloride (VCl3) (7718-98-1)
Vanadium trichloride is the inorganic compound with the formula VCl3. This purple salt is a common precursor to other vanadium(III) complexes.
Cobalt sulfide (1317-42-6)
cobalt sulphide · cobaltous sulfide · cobaltous disulfide
Cobalt sulfide is the name for chemical compounds with a formula CoxSy. Well-characterized species include minerals with the formula CoS, CoS2, Co3S4, and Co9S8. In general, the sulfides of cobalt are black, semiconducting, insoluble in water, and nonstoichiometric.
Nickel sulfide (1314-04-1, 12035-72-2, 11113-75-0, 16812-54-7)
millerite · nickel sulphide · nickel sulfide (2:1)
Nickel sulfide is the inorganic compound with the formula NiS. It is a black solid that is produced by treating nickel(II) salts with hydrogen sulfide. Many nickel sulfides are known, including the mineral millerite, which also has the formula NiS.
ZINC CHROMATE (13530-65-9)
zinc chromate (H2Cr2O7), Zn salt (1:1) · zinc chromate (Zn2(CrO4)O), monohydrate · zinc chromate (H2Cr2O7), Zn salt (1:1), trihydrate
Zinc chromate, ZnCrO4, is a chemical compound containing the chromate anion, appearing as odorless yellow powder or yellow-green crystals, but, when used for coatings, pigments are often added. It is used industrially in chromate conversion coatings, having been developed by the Ford Motor Company in the 1920s.
