Imine compound, novel catalyst for olefin polymerization, and process for producing olefin polymer

A compound represented by the following general formula (1):

• [In the formula, X represents a nitrogen atom, Y represents a nitrogen atom or a phosphorus atom,
• R5 and R6 each independently are a hydrogen atom or a hydrocarbon group which has 1-30 carbon atoms and may contain one or more heteroatoms, at least one of R5 and R6 being a hydrocarbon group which contains two or more heteroatom-containing groups, and
• R1 to R4 each independently represent a hydrogen atom, a hydrocarbon group which has 1-20 carbon atoms and may contain one or more heteroatoms, or a halogen atom, and two or more groups selected from among R1 to R4 may be linked to each other to form an alicyclic ring, an aromatic ring, or a heterocyclic ring which contains one or more heteroatoms selected from among oxygen, nitrogen, and sulfur atoms, in which each of the rings is a 5- to 8-membered ring which may have one or more substituents thereon.]
