In the crystal, O—H⋯O hydrogen bonds (O19—H19B⋯O21, O20—H20B⋯O13 and O20—H20A⋯O10iii; symmetry code as in Table 1 ▸) link the complex mol­ecule to the non-coordinating water mol­ecules (Fig. 1 ▸). Two crystallographically independent non-coordinating water mol­ecules are also linked to each other by O—H⋯O hydrogen bonds (O21—H21A⋯O20iv and O21—H21B⋯O20v; Table 1 ▸). Adjacent complex mol­ecules are connected by other O—H⋯O and N—H⋯O hydrogen bonds (N15—H15⋯O12i and O19—H19A⋯O9ii; Table 1 ▸). The above-mentioned inter­molecular inter­actions stabilize and link the components into a two-dimensional network parallel to the ab plane (Fig. 2 ▸).
