    The first rhodium complexes of diphosphinoazines [{RhCl(1,2-h:5,6-h- CH=CHCH2CH2CH=CHCH2CH2 )}2{m-R2PCH2C(But)=NN=C(But)CH2PR2] (R = Ph, Cy, Pri) were prepared by cleavage of the bridge in chloro(cycloocta-1,5-diene)rhodium(I) dimer, the analogous iridium(I) complexes were also prepared for the first time. The X-ray structures of isostructural rhodium and iridium complexes with bis(dicyclohexylphosphino)pinacoloneazine were determined. Diphosphinoazine ligands in the complexes remained in (Z,Z) configuration bridging two RhCl(C8H12) units.

    Štěpením můstku chloro(cyclookta-1,5-dien)rhodného dimeru byly připraveny první komplexy rhodia s difosfinoaziny [{RhCl(1,2-h:5,6-h- CH=CHCH2CH2CH=CHCH2CH2 )}2{m-R2PCH2C(But)=NN=C(But)CH2PR2] (R = Ph, Cy, Pri), poprvé byly rovněž připraveny analogické komplexy iridia. Rentgenovou difrakcí byly určeny struktury isostrukturních rhodných a iridných komplexů s bis(dicyklohexylfosfino)pinakolonazinem. Difosfinoazinové ligandy v komplexech zůstávají v (Z,Z) konfiguraci a můstkují dvě RhCl(C8H12) jednotky.
