The experimental electron density distribution in glycyl-L-threonine dihydrate has been investigated using single-crystal X-ray diffraction data at 110 K to a resolution of (sin theta/lambda) = 1.2 Angstrom(-1). Multipolar pseudo-atom refinement was carried out against 5417 observed data and the molecular electron density was analyzed using topological methods. The experimental electrostatic potential around the molecule is discussed in terms of molecular interactions. Crystal data: C6H12N2O4.-2H(2)O, M-r = 212.2, orthorhombic, P2(1)2(1)2(1), Z = 4, F(000) = 456 e, T = 110 K, a = 9.572 (3), b = 1.0.039 (3), c = 10.548 (2) Angstrom, V = 1013.6 (4) Angstrom(3), D-x = 1.3 g cm(-3), mu = 1.2 cm(-1) for lambda(Mo) = 0.7107 Angstrom.
