The title compound, C6H12O6, a C-3 position epimer of d-galactose, crystallized from an aqueous solution, was confirmed as β-d-pyran-ose with a (4) C 1 (C1) conformation. In the crystal, O-H⋯O hydrogen bonds between the hy-droxy groups at the C-1 and C-6 positions connect mol-ecules into a tape structure with an R 3 (3)(11) ring motif running along the a-axis direction. The tapes are connected by further O-H⋯O hydrogen bonds, forming a three-dimensional network.
标题化合物C6H12O6，即d-半乳糖的C-3位差向异构体，从水溶液中结晶出来，被确认为具有(4)C1(C1)构象的β-d-吡喃糖。在晶体中，C-1和C-6位羟基之间的O-H⋯O氢键将分子连接成带状结构，沿着a轴方向有一个R3(3)(11)环 motif。这些带通过进一步的O-H⋯O氢键相连，形成三维网络。
