Seven　new　metal-1,3,5-benzenetricarboxylate　coordination　polymers　have　been　synthesized　by　modification　of　auxiliary　components　during　the　assembly　reactions.　Their　structures　have　been　determined　by　single-crystal　X-ray　diffraction　analyses　and　further　characterized　by　XRD　and　TGA.　Interestingly,　they　show　fascinating　topological　structures.　Compounds　1　and　2　possess　the　undulating　layer　structure　with　3-connected　hcb　network　and　(3,6)-connected　kgd　network.　Compound　3　possesses　three-dimensional　(3D)　pillared-layer　structure　with　3-connected　2-fold　interpenetrating　srs　net.　Compound　4　also　has　the　3D　2-fold　interpenetrating　pillared-layer　structure;　however,　it　has　(3,5)-connected　hms　topology　because　the　Cd(II)　center　is　5-connected.　Compound　5　possess　3D　structure　through　hydrogen　bonding　interactions　between　ladder-like　layers.　Compounds　6　and　7　have　the　similar　3D　frameworks　with　4-connected　umc　net　and　(3,7)-connected　(3.4.5)(3(2).4(6).5(5).6(8))　topology,　respectively.　The　photoluminescent　properties　of　compounds　2-7　were　also　investigated.　(C)　2014　Elsevier　Inc.　All　rights　reserved.
