  A series of alkaline earth-metal organic frameworks(AE-MOFs),i.e.{[Mg2(μ6-L)(μ2-OH2)(H2O)4]·DMF}n(1),[Ca2(μ10-L)(EtO)]n(2),[Sr(μ6-H2L)(MeO)]n(3)and {[Ba1.5(μ5-H2L)(μ4-H3L)(H2O)3]·2(H2O)}n(4)were synthesized by employing a symmetrical V-shaped multicarboxylic acid ligand H4L(H4L = 5,5-oxydiisophthalic acid),resulting in versatile coordination modes as well as various topologies.
