Abstract
Two single and double chain manganese coordination polymers {[Mn（L1）（H2O）2]NO3}n（1） and [Mn（L2）2（H2O）]n（2）（HL1 = 2,2?:6?,2??-terpyridine-4?-carboxylic acid, HL2 = 4?-（4-carboxyphenyl）-2,2?:6?,2??-terpyridine） have been synthesized hydrothermally, and characterized by elemental analysis, IR spectroscopy, and X-ray single-crystal diffraction. Compound 1 crystallizes in monoclinic space group P2/c, while 2 crystallizes in triclinic, space group P1. Crystal data for 1: C16H14MnN4O7, Mr = 429.25, a = 10.684（2）, b = 9.338（1）, c = 9.896（2） ?, β = 113.89（3）o, V = 902.7（3） ?3, Z = 2, T = 153（2） K, Dc = 1.579 g/cm3, μ = 0.780 mm-1, F（000） = 438, R = 0.1084, wR = 0.3507, and GOF = 1.069; For 2: C44 H30 MnN6 O5, Mr = 777.68, a = 11.255（2）, b = 11.554（2）, c = 15.417（3） ?, α = 107.28（3）, β = 101.07（3）, γ = 107.23（3）o, V = 1740.2（6） ?3, Z = 2, T = 293（2） K, Dc = 1.484 g/cm3, μ = 0.440 mm-1, F（000） = 802, R = 0.0471, wR = 0.1050, and GOF = 0.948. In both compounds, the central Mn（Ⅱ） ions adopt the same distorted pentagonal-bipyramid geometry [MnN3O4] with different secondary structure units. L1 ligand adopts the μ2-1κ3N,N?,N??:2κ2O,O? mode to coordinate with mononuclear manganese to build a single chainlike compound 1, while L2 employs μ3-1κ3N,N?,N??:2κ2O,O?:3κ1O and 1κ1O modes to link dimeric Mn2O2 to exhibit a double chainlike 2.
