Abstract

The hydrothermal reaction of CuCl2·MoO, and 4,4′-bipyridylsulfide at 120°C for 72 h yields yellow needles of {Cu(S-py2)}4Mo8O26]·2 H2O (MOXI-36). The structure is constructed from {Cu4(S-py2)4}4+ squares and [Mo8O26]4- clusters linked through Cu-O bonds into a three-dimensional assembly. The framework structure evolves from the linking of each {Cu4(S-py2)4}4+ cluster to four adjacent molybdate clusters, each of which in turn connects to four cationic clusters. Furthermore, the dimensions of the cationic building block, ca. 12.7 Å on an edge, are sufficient to accommodate an interior anionic cluster, as well as the four clusters linked to the exterior surface. This produces a two-fold interpenetrated framework in which each {Cu4(S-py4)}4+ ring acts as a host to a [Mo8O26]4- cluster.
