crystallizes in the monoclinic space group P21/n with a= 11.705(2), b= 11.146(2), c= 16.317(5)Å, β= 93.16(2)°, and Z= 4. The two nitrogen atoms are indeed mutually cis to each other, the Pd–N distances being rather long [2.231 (3) and 2.223 (3)Å]; the phenyl ring which is a part of the seven-membered palladated ring is now perpendicular to the co-ordination plane of the Pd atom.
