New
barium–organic 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]·EtOH (7) can be replaced by the M′I4/M′I3 unit without compromising their basic
structural motifs, thus leading to the formation of the rare mixed
Cu–Ag iodometalates [Ba2(DMSO)12Cu4Ag4I12] (9) and [Ba(tetraglyme)2]2[CuAg7I12]·EtOH (10), respectively. In contrast, a breakdown in the structure-directing
properties of these iodometalates was observed in the mixed Ag–Pb
iodometalate [Ba(tetraglyme)2]2[Pb2Ag2I10]·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.
