Claim:
An organometallic compound (1) represented by the following general formula (1) (in the general formula (1), M is a magnesium atom, a zinc atom, an Al—R 11 group, or a Ga—R 11 group, provided that R 11 is a hydrogen atom, a hydrocarbon group, a halogen atom, a silicon-containing group, or an oxygen-containing group; R 1 and R 10 are each independently a hydrocarbon group having 1 to 20 carbon atoms, or R 1 and R 10 may be united with each other to form a divalent connecting group (R 101 ) having 4 or more carbon atoms and optionally containing a heteroatom excluding carbon and hydrogen and thus form a ring; R 2 to R 9 are each independently a hydrogen atom, or a hydrocarbon group having 1 to 20 carbon atoms; Q 1 and Q 3 are each independently a divalent hydrocarbon group; Q 2 is a divalent connecting group containing a linkage by a heteroatom excluding carbon; h, j, k, m, and p are each independently 0 or 1; n is an integer of 0 to 10; and r is an integer of 2 to 10000, provided that: R 1 to R 11 may be a group formed by substituting a part of the hydrogen atoms of the hydrocarbon group with a substituent containing a heteroatom excluding carbon and hydrogen; Q 1 and Q 3 may be a group formed by substituting a part of the hydrogen atoms of the divalent hydrocarbon group with a substituent containing a heteroatom excluding carbon and hydrogen; when h is 0, at least one of R 2 and R 3 is a hydrocarbon group having 2 to 20 carbon atoms; when h is 1, at least one of R 4 and R 5 is a hydrocarbon group having 1 to 20 carbon atoms; when p is 0, at least one of R 8 and R 9 is a hydrocarbon group having 2 to 20 carbon atoms; when p is 1, at least one of R 6 and R 7 is a hydrocarbon group having 1 to 20 carbon atoms; when n is 2 or more, plural Q 1 , Q 2 , Q 3 , j, k, and m may be individually the same as or different from one another; plural M may be the same as or different from one another; when plural R 11 are present, they may be the same as or different from one another; and plural Q 1 , Q 2 , Q 3 , h, j, k, m, n, p, and R 2 to R 9 may be individually the same as or different from one another.
