• wherein M is a Group 4 transition metal of Ti, Zr, or Hf;
• each of X1 and X2 is independently halogen, C1-20 alkyl, C2-20 alkenyl, C2-20 alkynyl, C6-20 aryl, C7-40 alkylaryl, C7-40 arylalkyl, C1-20 alkylamido, C6-20 arylamido, or C1-20 alkylidene, with the proviso that, when one of X1 and X2 is C1-20 alkylidene, then the other is absent;
• X3 is halogen C1-20 alkyl, C2-20 alkenyl, C2-20 alkenyl, C6-20 aryl, C7-40 alkylaryl, or C7-40 arylalkyl;
• each of R1 to R6 is independently hydrogen, substituted or unsubstituted C1-20 alkyl, substituted or unsubstituted C2-20 alkenyl, substituted or unsubstituted C2-20 alkynyl, substituted or unsubstituted C6-20 aryl, substituted or unsubstituted C7-40 alkylaryl, substituted or unsubstituted C7-40 arylalkyl, or substituted or unsubstituted C1-20 silyl, or
• R1 and R2, R2 and R3, R4 and R5, or R5 and R6 are linked together to form a substituted or unsubstituted C5-14 ring, and
• A is aluminum or boron;

• each of G1 and G2 is independently an element of Group 5 or Group 6 of the Periodic Table;
• and
• each of Q1 to Q6 is independently hydrogen, substituted or unsubstituted C1-20 alkyl, substituted or unsubstituted C2-20 alkenyl, substituted or unsubstituted C2-20 alkynyl, substituted or unsubstituted C6-20 aryl, substituted or unsubstituted C7-40 alkylaryl, substituted or unsubstituted C7-40 arylalkyl, or substituted or unsubstituted C1-20 silyl, or
• any two of Q1 to Q3 or any two of Q4 to Q6 are linked together to form a substituted or unsubstituted C5-14 ring comprising or not comprising a heteroelement,
• with the proviso that, when G1 is an element of Group 6 of the Periodic Table, then any one of Q1 to Q3 is absent, and when G2 is an element of Group 6 of the Periodic Table, then any one of Q4 to Q6 is absent,
• wherein each substituent is independently halogen, C1-20 alkyl, C2-20 alkenyl, C2-20 alkynyl, C6-20 aryl, C7-40 alkylaryl, C7-40 arylalkyl, C1-20 alkylamido, C6-20 arylamido, or C1-20 alkylidene.
