A　series　of　vanadium　selenites　covalently　bonded　with　metal-organic　complex,　namely,　Ni(2,2-bipy)2V2O4(SeO3)2　(1),　Cu(2,2-bipy)V2O4(SeO3)2·0.5H2O　(2)　and　Cu2(2,2-bipy)2V5O12(SeO3)2　(3)　(2,2-bipy=2,2-bipyridine)　have　been　hydrothermally　synthesized　and　structurally　characterized.　They　exhibit　three　different　structural　dimensions,　from　0D　cluster,　1D　chain　to　2D　layer.　Compound　1　features　a　0D　{Ni(2,2-bipy)2V2O4(SeO3)2}2　dimeric　cluster　composed　of　two　{Ni(2,2-bipy)2}2+　moieties　connected　by　the　{V4O8(SeO3)4}4-　cluster.　Compound　2　shows　a　1D　{Cu(2,2-bipy)V2O4(SeO3)2}n　chain　in　which　the　{Cu2(2,2-bipy)2}4+　moieties　are　bridged　by　the　{V4O8(SeO3)4}4-　clusters.　Compound　3　displays　a　2D　structure　consisted　of　mixed　valence　vanadium　selenites　layers　{VIVVV4SeIV2O18}n4-　and　{Cu(2,2-bipy)}2+　complex　moieties.　The　adjacent　layers　are　further　interconnected　via　π-π　interactions　between　the　2,2-bipy　ligands　exhibiting　an　interesting　3D　supramolecular　architecture.　Both　compound　1　and　2　contain　a　new　{V4O8(SeO3)4}4-　cluster　and　compound　3　exhibits　the　first　2D　vanadate　polyhedral　layer　in　vanadium　selenites/tellurites　with　organic　moieties.　©　2016　Elsevier　Inc.　All　rights　reserved.
