 Title    A Further Example for the Validity of the Concept of Unit Construction in Polyoxometalate Chemistry  
 Abstract    The compound Na7[NaC{(M 0V20 4)3()U2-0 H)3H(PhP03)4}2] • 2 N2H4-26 H20 (formu­ lation with respect to the aggregate in the crystal) has been synthesized and character­ ized by single-crystal X-ray structure analysis (which alone does not allow the determi­ nation of the formula), UV/Vis/NIR/IR, 31 P{1H}, 'H and 23Na NMR spectroscopy as well as magnetic susceptibility measurements. The compound is formed under similar conditions as (NH2Me2)6[H2C(Mov204)604(/i2-C)H)i2(MoVIC)3)4]-Correspondingly, both cluster frame­ works are built up by the same {(Mov204)3(/i2-OH)3}3+ units.

 Title    Eindimensionale Kupfer(II)-Koordinationspolymere: Kristall-Engineering durch variable Verknüpfungsmuster [1] One Dimensional Copper(II) Coordination Polymers: Crystal Engineering through Variable Types of Linkage [1]  
 Abstract    of a methanolic copper(II) acetate solution with tetrazolyl enol derivatives 2a or 2b leads to the formation of the corresponding lD-coordination polymer ^[CuL2] 3a and pseudo lD-coordination polymer [CuL2]2 3b, respectively. On the contrary, reaction of 2c with methanolic copper(II) acetate solution yields OH-bridged lD-coordination polymer ^[CuL2(MeOH)2l 3c. Single-crystal X-ray diffraction of the supramolecular species 3 established unequivocally the structures of the stairlike coordination compounds. Reaction of a methanolic copper(II) acetate solution with amidotetrazole derivative 6 leads to the formation of the lD-coordination polymer ^,[CuL2] 7. The structure of 7 has been established by X-ray structure analysis.
