The invention describes electronic devices comprising a metal complex compound having at least one anionic ligand containing two P donors, having the formula (I), in which R1 to R4 are, independently of one another, an atom or radical from the group comprising hydrogen, a halogen, R, RO&#x2014;, RS&#x2014;, RCO&#x2014;, RCOO&#x2014;, RNH&#x2014;, R2N&#x2014;, RCONR&#x2014; and &#x2014;Si(R)X(OR)3-X, where R=a C1-C40-hydrocarbon and X=1, 2 or 3, and E is a bridge atom from the group with carbon or boron, where an atom or radical from the group with hydrogen, halogen, &#x2014;CN, R, RO&#x2014;, RS&#x2014;, RCO&#x2014;, RCOO&#x2014;, RNH&#x2014;, R2N&#x2014;, RCONR&#x2014; and &#x2014;Si(R)X(OR)3-X, where R=the C1-C40-hydrocarbon and X=1, 2 or 3, is optionally bonded to the carbon, and two radicals from the group with halogen, R, RO&#x2014;, RS&#x2014;, RCO&#x2014;, RCOO&#x2014;, RNH&#x2014;, R2N&#x2014;, RCONR&#x2014; and &#x2014;Si(R)X(OR)3-X, where R=the C1-C40-hydrocarbon and X=1, 2 or 3, are optionally bonded to the boron. The invention furthermore describes a process for the production of an electronic device of this type and processes for the generation of light or blue emission using a metal complex compound of this type.
