Group 3 metal catalyst system and process to produce ethylene polymers therewith

A catalyst compound represented by the formula (I):

• where M is a group 3 metal;
• M* is a group 3 metal;
• each R1, R2, R3, R4, R5, R9, R10, R12, R13, and R14 is, independently, hydrogen, a hydrocarbyl, or a substituted hydrocarbyl, where adjacent R groups optionally form cyclic fused ring systems;
• each R7 and R15 is, independently,
• —O(R*)— where R* is independently hydrogen, halogen, linear hydrocarbyl, or substituted hydrocarbyl, or -E(R)n—, where E is carbon, silicon, germanium, nitrogen, phosphorus, sulfur, or halogen;
• n is 0, 1, 2, or 3;
• each R is independently hydrogen, halogen, hydrocarbyl, or substituted hydrocarbyl;
• when E is C, Si, or Ge, then n is 2 or 3;
• when E is N or P, then n is 2;
• when E is S, then n is 1;
• and when E is halogen, n is 0;
• and
• each R6 and R8 is, independently, a hydrogen, halogen, hydrocarbyl, substituted hydrocarbyl, or silylcarbyl.
