| Abstract: | Two new supramolecular complexes MnL(H2O)4] (1) and ZnL(H2O)5]·O.25H2O(2) (H2L=5-carboxy-1-earboxymethyl-2-oxidopyridinium) have been synthesized and structurally characterized by elemental analysis, IR and X-ray single-crystal structure determination. Complex 1 crystallizes in the monoclinic system, space group P21/n with a=5.1537(2), b=21.2008(9), c=10.9727(4) (A), β=99.182(2)°, V=1183.54(8) (A)3, C8H13MnNO9, Mγ=322.13, Dc=1.808,Z=4, F(000)=660, μ=1.160, R=0.0372 and wR=0.0750 for 2217 observed reflections (I＞2σ(I)). Complex 2 crystallizes in the triclinic system, space group P1 with α=7.730(2), b=8.030(2), c=11.400(2) A, α=104.27(3), β=92.93(3), γ=102.67(3)°, V=664.9(2) A3, C8H15.5ZnNO10.25, Mγ=355.08, Dc=1.774, Z=2, F(000)=365,μ=1.899, R=0.0243 and wR=0.0695 for 2759 observed reflections (I＞2σ(I)). Their thermal properties have been studied. |
