摘　　要：A novel nickel（Ⅱ） complex with L-histidine has been synthesized and solved by single-crystal X-ray diffraction analysis at physiological pH. The title complex （C7H16NiN4O6S, Mr = 343.01） crystallizes in monoclinic, space group P21 with a = 7.2194（7）, b = 7.5968（7）, c = 12.2797（11） A, β = 93.3110（10）°, V = 672.35（11） A^3, Z = 2, Dc= 1.694 g/cm^3, F（000） = 356, μ（MoKα） = 1.626 mm^-1, T = 293（2） K, the final R = 0.0184 and wR = 0.0426 for 2207 observed reflections with 1 〉 2σ（I）. The complex provides insights into a possible structural arrangement between nickel （Ⅱ） and L-histidine which may be physiologically important and abundantly present in biological systems.A novel nickel（Ⅱ） complex with L-histidine has been synthesized and solved by single-crystal X-ray diffraction analysis at physiological pH.
