    Abstract

    Hydrous crystals of [{PdII(bpy)}2(μ-x-tart)] ·nH2O (bpy: 2,2'-bipyridine; tartH2 2-: tartrate; 1a: x = l, n = 6; 2a: x = d, n = 6; 3a: x = dl, n = 4; 4a: x = meso, n = 4) and anhydrous crystals of [{PdII(bpy)}2(μ-l-tart) ] (1b) were isolated from aqueous and MeOH solutions, respectively. X-ray crystallography revealed the stacked structures of clamshell-like dinuclear units in 1a-3a and 1b, where intramolecular metal-metal and π-π stacking interactions were observed. Right- and left-handed helically stacked columns were formed in the 1a and 2a crystals, respectively. The significant role of hydrogen bonding among lattice water molecules and tartrate is suggested because 1b exhibited a zigzag arrangement only through intermolecular metal-metal interactions. In 3a, l- and d-tart units stacked alternately in a zigzag arrangement with intermolecular π-π interactions. In 4a, dimeric aggregates of the twisted dinuclear units further formed a 2D sheet architecture.
