Octahedral, liquid‐crystalline complexes of 1,4‐diazabutadienes with rhenium(I)**

Mesomorphic tansition metal complexes have been shown in the past to exhibit technically interesting properties, including a igh birefringence, high linear and nonlinear polarizability, and igh linear dichroism. Here, a general approach to the design and synthesis of metal‐containing liquid crystals based on high coordination number centers is presented. Diazautadienes are used as the ligands for the generation of the complexes and it is thought that they will find wide applicability in he design of new metallomesogens.
