Hexazine complexes

Hexazine is reported to have been isolated in a matrix at low temperatures by photolysis of the complex cw-(Pt(N3)2(PPh3)2) <80AG(E)7I7> however, it has been suggested that this result requires verification <83JST(l4)35i>. 

Hexazine has been reported to be formed by the low temperature photolysis of a platinum complex <80AG(E)717), although its existence has been questioned <83JST(14)35l>. However, thorough theoretical studies of the system have been made. 

There are no published works from the last decade on the preparation of the parent pentazine 3 and hexazine 4 systems or their derivatives. Both compounds have received extensive theoretical treatment, including some hexazine derivatives, such as the Woxides <2001PCA7693> or transition metal complexes <2002CPL531>.
