New barium鈥搊rganic derivatives are introduced as countercations in the iodocuprates and -argentates to yield novel hybrids with unique structural motifs and bonding modes, many of them also showing vivid fluorescence on exposure to UV light. The tetrahedral MX4/trigonal-coplanar MX3 unit in these hybrids [Ba2(DMSO)12Cu8I12] (1) and [Ba(tetraglyme)2]2[Ag8I12]路EtOH (7) can be replaced by the M鈥睮4/M鈥睮3 unit without compromising their basic structural motifs, thus leading to the formation of the rare mixed Cu鈥揂g iodometalates [Ba2(DMSO)12Cu4Ag4I12] (9) and [Ba(tetraglyme)2]2[CuAg7I12]路EtOH (10), respectively. In contrast, a breakdown in the structure-directing properties of these iodometalates was observed in the mixed Ag鈥揚b iodometalate [Ba(tetraglyme)2]2[Pb2Ag2I10]路2Me2CO (11), where the basic structure of the synthon [Ba(tetraglyme)2]2[Ag4I8] (8) was not retained due to the compulsory molecular rearrangement required as a result of replacing AgI4/AgI3 units with octahedral PbI6 units.
