In the centrosymmetric title compound, C(20)H(24)N(2)O(6)S(2), the N-H and C=O bonds are trans to each other. In the crystal, inter-molecular N-H⋯O(S) hydrogen bonds link the mol-ecules into zigzag chains running along the b axis. The O atom involved in the hydrogen bond has a longer S-O bond than the other O atom bonded to S [1.441 (2) versus 1.428 (2) Å].
在中心对称的标题化合物C₂₀H₂₄N₂O₆S₂中,N-H键和C=O键彼此呈反式。在晶体中,分子间的N-H⋯O(S)氢键将分子连接成沿b轴延伸的锯齿链。参与氢键的O原子的S-O键长比与S键合的另一个O原子的S-O键长更长[1.441 (2) Å对1.428 (2) Å]。
