Abstract: Metallocene compounds of formula (I) are new. In (I), Cp = optionally substituted cyclopentadienyl; Ind = optionally substituted indenyl; M = tetravalent metal; R -R = H or 1-20C hydrocarbyl; m = 1 or 2; k, l = 1 if m = 1; k, l = 0 if m = 2. Also claimed are (i) catalysts (I-A) containing compound(s) (I) and cocatalyst(s), (ii) a process for the production of polyolefins by polymerisation of olefins in presence of these catalysts, (iii) polyolefins obtained by this process, (iv) moulded products containing these polyolefins, and (v) a process for the production of (I) by reacting compounds of formula (II) with compounds of formula M(NR 2NR 2NR3 NR 2) (III). The preferred cocatalyst is an aluminium and/or boron compound. The catalyst may also contain a support, and metallocene (I) may be prepolymerised.
