Two　novel　Ag　coordination　polymers　based　on　tetrazole-yl　acylamide,　Ag(NTAA)　(1,　H-NTAA　=　N-(1H-tetrazol-5-yl)acetamide)　and　Ag(NTPA)　(2,　H-NTPA　=　N-(1H-tetrazol-5-yl)propionamide)　have　been　synthesized　under　solvothermal　conditions　and　characterized　by　single-crystal　X-ray　diffraction.　Compound　1　features　a　3-connected　4.8(2)-fes　network　and　compound　2　displays　a　ladder-like　chain.　The　different　structures　between　1　and　2　are　mainly　related　with　the　substituent　groups　of　tetrazole-yl　acylamide.
