文摘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).
