abstract = {The study of phase formation in the U-Te-O systems with
mono and divalent cations under high-temperature
high-pressure (HT/HP) conditions has resulted in four new
inorganic compounds: K2[(UO2)(Te2O7)], Mg[(UO2)(TeO3)2],
Sr[(UO2)(TeO3)2] and Sr[(UO2)(TeO5)]. Tellurium occurs as
TeIV, TeV, and TeVI in these phases which demonstrate the
high chemical flexibility of the system. Uranium (VI) adopts
a variety of coordinations, namely, UO6 in K2[(UO2)(Te2O7),
UO7 in Mg[(UO2)(TeO3)2] and Sr[(UO2)(TeO3)2], and UO8 in
Sr[(UO2)(TeO5)]. The structure of K2[(UO2)(Te2O7)] is
featured with one dimensional (1D) [Te2O7]4- chains along
the c-axis. The Te2O7 chains are further linked by UO6
polyhedra, forming the 3D [(UO2)(Te2O7)]2- anionic
frameworks. In Mg[(UO2)(TeO3)2], TeO4 disphenoids share
common corners with each other resulting in infinite 1D
chains of [(TeO3)2]4- propagating along the a-axis. These
chains link the uranyl bipyramids by edge sharing along two
edges of the disphenoids, resulting in the 2D layered
structure of [(UO2)(Te2O6)]2-. The structure of
Sr[(UO2)(TeO3)2] is based on 1D chains of
[(UO2)(TeO3)2]∞2− propagating into the c-axis. These
chains are formed by edge-sharing uranyl bipyramids which
are additionally fused together by two TeO4 disphenoids,
which also share two edges. The 3D framework structure of
Sr[(UO2)(TeO5)] is composed of 1D [TeO5]4− chains sharing
edges with UO7 bipyramids. Three tunnels based on 6-Membered
rings (MRs) are propagating along [001], [010] and [100]
directions. The HT/HP synthetic conditions for the
preparation of single crystalline samples and their
structural aspects are discussed in this work.},
