Most notably, the binuclear complex exhibited one Co(II) ion in a strongly distorted pyramidal coordination environment while the second Co(II) ion was placed in an only slightly distorted tetrahedral coordination sphere. This feature is enabled through the different chelation modes of the four TMSAMAPY ligands. While two of the ligands coordinated to one Co(II) ion each in the way earlier observed by Glatz in octahedral, mononuclear [Co(TMSMAPY)2(TBUPY)2],
