Two new transition metal compounds,[Mn(dpa)2(tmd)2]n(1,H2dpa=4-hydroxy-phenyl-acetic acid,tmd=4,4-trimethylenedipyridine)(A)nd[Co4(dpa)6(tmd)4(H2O)4]nnH2O.nCl2(2),have been synthesized by hydrothermal synthesis.Compound 1 crystallizes in the monoclinic system,space group P21/n with a=9.828(3),b=17.493(5),C=11.616(4)(A),β=110.146(6)0,V=1874.9(10)(A)3,C42H42MnN4O6,Mr=753.74,Z=2,Dc=1.335 g/cm3,μ=0.406mm-1,F(000)=790,the final R=O.1047 and wR=0.2021 for 2698 observed reflections(I>2σ(I)).Compound 2crystallizes in the monoclinic system,space group P2l/c with a=11.7214(13),b=17.1582(19),C=24.625(3)(A),β=103.055(3)0,V=4824.4(9)(A)3,C100H104Cl2Co4N8O23,Mr=2094.55,Z=2,Dc=1.443 g/cm3,μ=0.809mm-1,F(000)=2180,the final R=0.0550 and wR=0.0673 for 4104observed reflections(I>2σ(I)).These complexes were characterized by elemental analysis,IR spectroscopy,and X-ray single-crystal diffraction.The structural analyses show that the two com-pounds are both one-dimensional chain structures.However,compounds 1 and 2 form three-dimensional supramolecular structures by hydrogen bonds,respectively.
