| Abstract: | Two new tetrahedral tungsten cyanide cluster compounds, [Cu(dien)]3[W4Te4(CN)12] · 9H2O (1) (dien=diethylenetriamine) and [Ni(en)(NH3)]3[W4Se4(CN)12] · 7.5H2O (2) (en=ethylenediamine), were synthesized by treating aqueous solutions of the saltlike cluster compound K6[W4Te4(CN)12] · 5H2O/K6[W4Se4(CN)12] · 6H2O with copper(II)/nickel(II) chloride in aqueous ammonia containing dien/en. The cyano-bridged layered coordination polymeric compounds were characterized by single-crystal X-ray diffraction analysis: monoclinic, space group P21 for 1; trigonal, space group  for 2. Structures of 1 and 2 consist of infinite neutral layers of cluster components {W4Te4(CN)12}/{W4Se4(CN)12} connected, one another by {Cu(dien)} or {Ni(en)(NH3)} fragments, respectively. |
