SPECIFIC COMPOUNDS - 6 Compounds (I) are disclosed e.g. copper complex of formula (Iaa)-(Icc), iridium complex of formula (Idd) and tungsten complex of formula (Iee).    EXAMPLE - A suspension of a cyclic ligand of formula (A) (3.3 g), copper (I) iodide (1.9 g) and glass beads (50 g, 4 mm diameter) in dichloromethane (200 ml) was stirred for 24 hours at room temperature. The resulting mixture was filtered through a coarse sieve and dichloromethane was evaporated under vacuum. Then the resulting mixture was stirred with ethanol (50 ml) for 2 hours, and filtered to give copper complexes (Iaa) (4.7 g).
