Metal dithiocarbamate precursors for the preparation of a binary sulfide and a pyrochlore: Synthesis, structure, continuous shape measure and bond valence sum analysis of antimony(III) dithiocarbamates

Nano Sb2S3(20 nm) and (Tl+2/3−2δ)[Tl3+1−ySb3+y]Sb2O6O′1/3−δ, a pyrochlore, have been prepared from three antimony(III)-dithiocarbamate precursors and have been characterized by PXRD, FESEM, EDX, HRTEM and SAED. The dithiocarbamate precursors show distorted octahedral and pentagonal pyramidal geometries around antimony. CShM analysis of the structural data support the distorted geometries.
