Cobalt oleate is an organometallic compound with the formula Co(C₁₈H₃₃O₂)₂. When cobalt oleate is added to non-polar solvents, the viscosity rapidly increases, and then continues increasing over time. This unusual viscosity effect is caused by the formation of a weak coordination complex with the solvent molecules.^[1]

Preparation

Cobalt oleate can be synthesized by heating a solution of sodium oleate and cobalt(II) chloride to 70 °C.^[2]

$2 N a C_{18} H_{33} O_{2} + C o C l_{2} ⟶ 2 N a C l + C o (C_{18} H_{33} O_{2})_{2}$
