A new 1D chain copper coordination polymer[Cu_2(H2L)_2(C_(10)H_8N_2)(H_2O)_2]_n·3n(H_2O)with 2,3-pyridinedi carboxylic acid(H2L)and 2,2’-bipyridine(2,2’-bipy)as ligands has been synthesized in the mixed ethanol and water solvents.Crystal data for this complex are as follows:monoclinic,space group P2_1/c,a=7.7713(7),b=27.478(3),c=13.2621(13)A,β=100.6940(10)°,V=2782.8(5)A~3,D_c=1.722 g/cm~3,Z=4,μ=1.61 mm~(-1),F(000)=1472,the final R=0.0363 and wR=0.0933.In the crystal structure,the whole molecule consists of two cooper ions,two H2L,one2,2’-bipy molecule and six water molecules.Each central copper ion is coordinated with three oxygen atoms from two H2L and one water molecule,two nitrogen atoms from one 2,2’-bipy molecule and two H2L,giving a distorted tetragonal pyramidal geometry.Thermal stability properties of the complex were investigated.
A New 1D chain copper coordination polymer [Cu_2 (H2L) _2 (C_ (10) H_8N_2) (H_2O) _2] _n · 3n (H_2O) with 2,3-pyridinedi carboxylic acid (H2L) and 2,2’-bipyridine 2,2’-bipy) as ligands has been synthesized in the mixed ethanol and water solvents. Crystal data for this complex are as follows: monoclinic, space group P2_1 / c, a = 7.7713 (7), b = 27.478 (3) , C = 13.2621 (13) A, β = 100.6940 (10) °, V = 2782.8 (5) A ~ 3, D_c = 1.722 g / cm ~ 3, Z = 4 and μ = 1.61 mm ~ F (000) = 1472, the final R = 0.0363 and wR = 0.0933.In the crystal structure, the whole molecule consists of two cooper ions, two H2L, one2,2’-bipy molecule and six water molecules .ach central copper ion is coordinated with three oxygen atoms from two H2L and one water molecule, two nitrogen atoms from one 2,2’-bipy molecule and two H2L, giving a distorted tetragonal pyramidal geometry. Thermomal stability properties of the complex were investigated.
