摘要
A novel multisublattice compound,[Ni(OH)1.115(H2O)0.885]1.22(Ti1.73O4)·1.65H2O,was hydrothermally synthesized with K0.81Li0.27Ti1.73O4 as the precursor.This compound was characterized by XRD,IR,TG-DTA and TEM.In this compound,the TiO2 layers and Ni(OH)2 layers alternately stack together along the c direction,and three sublattices were formed.One is TiO2 sublattice,which is orthorhombic with possible space group Pmmm,the lattice parameters are a=0.3875 nm,b=0.2976 nm,c=2.288 nm and α=β=γ=90°.The other two are Ni(OH)2 sublattices which have the same dimensions and symmetry,the lattice parameters are a=b=0.3140 nm,c=2.288 nm,α=β=90° and γ=120°.TiO2 sublattice and Ni(OH)2 sublattice are incommensurate in two dimensions in the ab plane.This result confirms that it is possible to design and synthesize more complicated misfit layered compounds based on the layered compounds by the soft chemical method.
