    Abstract: A cis-bridged metal complex (I) of formula (1) is claimed. Also claimed are (i) a process for the production of (I) by ligand exchange of metal salts and metal complexes and optionally transformation of the resulting complex to a cationic complex. The ligand exchange reaction is carried out using chelate ligands (II) of formula (2). (ii) Chelate ligands (II) . R = H, 1-20C hydrocarbon, 3-30C organosilicon, or NR R ; q = 0-20 R', R", R -R = H, 1-20C hydrocarbon or 3-30C organosilicon; M = Group VIIIB metal; E , E , Z = Group VA element; R -R = 1-20C hydrocarbon or 3-30C organosilicon; A , B = 1-4C alkylene, silylene bridged organic group or NR ; L , L = ligand, with proviso that L = L = Cl when R is not equal to (3); x = anion; p, m, n = 0-4; and p = m x n
