Abstract

The new compound [Pd(NH2CH2CH2OH)4][Pd6(NH2CH2CH2S)8]Cl6 · 5H2O (I) is synthesized and its crystal structure is determined. The crystals are monoclinic, a = 25.625(6) Å, b = 9.633(5) Å, c = 24.847(7) Å, β = 91.47(2)°, Z = 4, and space group C2/c. The structural units of crystals I are the centrosymmetric hexanuclear [Pd6(NH2CH2CH2S)8]4+ cations, the mononuclear [Pd(NH2CH2CH2OH)4]2+ cations with C 2 symmetry, the Cl− anions, and crystallization water molecules. In the hexanuclear cation, the interaction between the Pd atoms occurs through the S atoms of the mercaptoethylaminate ligands. The Pd(2) and Pd(3) atoms and the ligands form two metallochelate fragments in which the N and S atoms are located in cis positions. The average lengths of the Pd-S and Pd-N bonds are equal to 2.274(1) and 2.074(6) Å, respectively. The metallochelate fragments are joined to each other and to their centrosymmetric analogues through the Pd(1) atom, which coordinates four S atoms [the average Pd-Sav bond length is 2.332(1) Å]. In the mononuclear cation, the Pd(4) atom coordinates four N atoms of the monoethylaminate ligands [the Pd-N bond lengths are 2.045(6) and 2.056(6) Å]. The shortest Pd⋯Pd distance is equal to 3.207(1) Å. The bonding in the structure is provided by numerous hydrogen bonds with the participation of all the H2O molecules, NH2 groups, and Cl− anions.
