Mr=520.15, monoclinic, P21/n, a=7.207(2), B=20.616(4), c=5.854(1) A, β=96.05(1)º, V=864.9(6)A3, Z=2, Dx=2.00 Mg m-3, Mo Ka, = 0.71069 A, µ=2.553 mm-1, F(000)=512, 298 K, R=0.060 for 1492 reflections. (II): Mr=947.07, triclinic, Pl, a=12.666(7), b=10.595(6), c=6.572(5)A, a=98.30(2), = 97.04(2), = 99.84(2)º, V=850(2)A3, Z=1, Dx=1.85 Mg m-3, Mo Ka, =0.71069 A, µ=1.958 mm-1, F(000)=490, 298 K, R=0.071 for 1879 reflections. (I) was solved by direct methods, using MULTAN and DIRDIF, (II) by the heavy-atom method. The four-membered Pd, S, Pd, S rings have a syn-exo conformation, with dihedral angles between the S, Pd, S planes of 154.4(2) and 133.0(3)º for (I) and (II), respectively.
