palladium(II) complexes of the types [(1,2,4)PdCl2] (5a, 6a, 7) and [(1,2,3,4)Pd(NCCH3)x](Y)2 (5b, 5c, 6b, 6c, 8, 9), x=0, 2; Y=BF4 −, NO3 − is reported. The dicationic palladium(II) complex [Pd(DBQED)(NO3)2·H2O] (5c) crystallizes in the monoclinic space groups P21/c (no. 14) with a=11.458(1), b=15.302(1) Å, c=20.644(2) Å, β=99.23(1)° and V=3572.7 Å3, Z=4. All four nitrogen donors are attached to the Pd(II)-center
