IN HONOR OF PROFESSOR GALEN STUCKY ON THE OCCASION OF HIS 65TH BIRTHDAY
The hydrothermal reaction of di-2-picolylamine (pca), MoO 3 and NiSO 4 '6H 2 O yielded the bimetallic oxide cluster [{Ni (pca)(H 2 O)} 2 Mo 8 O 26 ]'2H 2 O (1'2H 2 O). Similarly, the reaction of pca, MoO 3 and CuSO 4 '5H 2 O produced the twodimensional material [{Cu (pca)} 2 Mo 8 O 26 ] (2). The structure of 1 consists of -{Mo 8 O 26 } 4؊ clusters, decorated with {Ni (pca)(H 2 O)} 2؉ subunits, linked to terminal molybdenyl {Mo؍O} moieties. The structure of 2 also contains -{Mo 8 O 26 } 4؊ clusters as building blocks; however, in this instance, the {Cu (pca)} 2؉ subunits serve to bridge adjacent clusters into a two-dimensional network. The hydrothermal reaction of pca and CuSO 4 '5H 2 O with MoO 2 in place of MoO 3 produced [{Cu 3 (pca) 3 MoO 4 } Mo 8 O 26 ]'2H 2 O (3'2H 2 O), a one-dimensional material, constructed from -{Mo 8 O 26 } 4؊ clusters linked through unusual {Cu 3 (pca) 3 MoO 4
