Three hydrogen bond networks of cobalt（II） coordination polymers { [Co（btp）2（H2O）2]·2（l,2-Hbdc）·2H2O}n （1）, { [Co（btp） （1,3 -bdc）（H2O）]·1.5H2O } n （2） and { [Co（btp）2（H2O）2]·...Three hydrogen bond networks of cobalt（II） coordination polymers { [Co（btp）2（H2O）2]·2（l,2-Hbdc）·2H2O}n （1）, { [Co（btp） （1,3 -bdc）（H2O）]·1.5H2O } n （2） and { [Co（btp）2（H2O）2]·（1,4-bdc） } n （3） were synthesized by 1,3 -bis（1,2,4- triazol- 1-yl）propane （btp） and benzenedicarboxylate position isomers. Complex 1 is comprised of [Co（btp）z（H20）]2n＋ 1D cation chains, 1,2-Hbdc anions and lattice water molecules. The structure of 2 is an undulated 2D （4,4） network. Two adjacent networks interpenetrate each other to form a new 2D double-layers network which is sustained by the hydrogen bond interactions in 2. Complex 3 is comprised of [Co（btp）z（H20）]n2n＋ 1D cation chains and 1,4-bdc2 anions. These [Co（btp）2（H2O）]n^2＋ 1D cations and 1,2-Hbdc-/1,4-bdc2- anions form 2D hydrogen bond networks in 1 and 3. The thermal stabilities of 1, 2 and 3 were investigated.展开更多
