Homochiral　framework　materials　are　of　current　interest　due　to　their　potential　applications　in　asymmetric　catalysis　and　enantioselective　separation.　Four　new　Cd(II)　camphorates　(1-4)　with　2,2＇-bipyridine　ligand　(=　2,2＇-bipy)　are　successfully　synthesized　and　show　distinct　structural　features.　Such　rich　Cd-cam-2,2＇-bipy　system　is　composed　of　four　compounds,　[Cd(D-cam)(2,2＇-bipy)(DMF)](n)　(1),　[Cd(D-cam)(2,2＇-bipy)(H2O)](n),　(2),　[Cd-2(D-cam)(2)(2,2＇-bipy)(2)](n)　(3)　and　[Cd2Cu2(D-cam)(4)(2,2＇-bipy)(2)](n)center　dot　4H(2)O　(4),　which　are　obtained　under　different　conditions.　Both　compounds　1　and　2　show　infinite　homochiral　Cd-camphorate　chain,　while　compounds　3　and　4　exhibit　homochiral　layered　structures　based　on　different　dinuclear　units.　The　results　demonstrate　the　rich　coordination　chemistry　of　the　enantiopure　D-camphorate　ligand　and　the　structural　diversity　of　metal-camphorate　compounds.　(C)　2012　Elsevier　Masson　SAS.　All　rights　reserved.
