Two crystalline silver alkynyl assemblies, namely, [Ag6(tBuC---C)4 L1]n (1), [Ag10(tBuC---C)6(L2)2]n (2) (H2L1 = 1,8-naphthalene dicarboxylic acid and H2L2 = 1,4-naphthalene dicarboxylic acid) have been obtained by the reaction of polymeric [tBuC---CAg]n with silver salts and dicarboxylic acids under mild solvothermal conditions. Compounds 1 and 2 are coordination polymers of irregular silver alkynyl clusters. 1 is chains of cube-like silver clusters connected with L1 and tBuC---C- ligands. In compound 2, the Ag10 clusters surrounded by six tBuC---Cligands are linked by silver atoms to 1D chains, which are further extended by L2 ligands to a rare 3D framework. From the topological view, the structure of 2 can be regarded as alpha-Po topology. The luminescence properties indicated that the two complexes display more than one peak maxima at 298 K using 335 nm excitation.
