Popis:	The crystal structure of [{Pd(acac)(NHEt2)2}+(acac)−] at −170°C was determined by means of X-ray diffraction. The crystal belongs to monoclinic system: a=13.905(3), b=12.901(4), c=12.205(3) A, β=96.28(2)°, space group I2/c with Z=4. The structure was established by the heavy atom method and refined anisotropically by the least-squares procedure; R=0.044 for 1558 non-zero reflections. Both the {Pd(acac)(NHEt2)2}+ cation and (acac)− anion lie on the crystallographic two-fold axis. The cation and anion lying on the same two-fold axis are bound together by two hydrogen bonds [N–H···O(2)=N′–H′···O(2′)=2.871(4) A] to form an ion-pair. Two ion-pairs mutually related by the crystallographic center of symmetry make a packing unit of the crystal.
