Claim 6:
7. The compound of claim 1, wherein CyC comprises a group of formula (3) or (4) and is selected from the group consisting of formulae (CyC-1-1) to (CyC-19-1) and/or CyD comprises a group of formula (3) or (4) and is selected from the group consisting of formulae (CyD 1-1) to (CyD-10-1):, wherein
X is on each occurrence, identically or differently, CR or N; and
W is on each occurrence, identically or differently, NR, O, S, or CR2;
in each case denotes the positions which stand for CR, wherein the respective radicals R, together with the C atoms to which they are bonded, form a ring of formula (3) or (4),

where the group of formulae (CyC-1-1) to (CyC-19-1) is in each case bonded to CyD at the position denoted by # and is coordinated to the metal at the position denoted by *, and where the groups of formula (CyD-1-1) to (CyD-10-1) is in each case bonded to CyC at the position denoted by # and
is coordinated to the metal at the position denoted by *.
