Dimerization of Incomplete Cubane-Type Mo3S4(DTP)3 Units Linked by Bridging α, ω-Dicarboxylate

Since the trinuclear molybdenum cluster compound Mo₃S₄(DTP)₃(μ-DTP)(L) (DTP=diethyldithiophosphate, L=loosely-coordinated ligand) was reported^[1],a large number of monomeric trinuclear molybdenum derivatives have been synthesized from it by its diverse substitution reactions^[2]. This reaction provides a useful route to design cluster complexes with specific functions. By the reaction with α, ω-dicarboxylates, we successfully synthesized the first oligomer containing two incomplete cubane-type[Mo₃S₄] cores formulated as[Mo₃S₄(DTP)₃(DMF)]₂[η²-μ-OOC(CH₂)₃COO-μ-η²]) whose molecule structure is as follows:     

Hydrothermal Synthesis and Structure of [(PbCl2)(μ-Pyz)1/2]n (Pyz = Pyrazine)

A novel 2-D lead-containing hybrid compound, [(PbCl2)(μ-Pyz)1/2]n (Pyz = pyrazine) 1, has been synthesized by the hydrothermal assembly of pyrazine with lead chloride.Elemental analysis and X-ray crystal structure analyses were carried out for the structural determination and characterization of the title compound. Compound 1 crystallizes in orthorhombic,space group Ibam, with a = 19.5558(18), b = 7.1939(6), c = 7.5449(6) (A), V = 1061.44(16) (A)3,C2H2Cl2NPb, Mr= 318.14, Z = 8, Dc= 3.982 g/cm3,μ = 32.63 mm-1, F(000) = 1096.0, R = 0.0368and wR = 0.0901 for 623 observed reflections (1 ＞ 2σ(Ⅰ)).
