A new crystalline complex zinc nickel sulfate heptahydrate (ZNSH) has been prepared. The crystal structure was investigated by x-ray single crystal diffraction method and the empirical formula is Zn_0.24Ni_0.76(SO₄)^.7H₂O. The ZNSH crystal belongs to the orthorhombic space group P2₁2₁2₁ with cell parameters a= 6.7742(14) Å, b= 11.748(2) Å, c= 12.009(2)Å. The deep-green ZNSH single crystal with dimension of 30×25×25mm³ has been grown by the cooling solution method. The constituent ratio of ZNSH crystal grown from various compounding solutions at temperature range 40-50°C is approximate invariant. The crystal absorption spectra with theoretical analysis are reported.
