In the title compound, trans-[PtCl2(C15H15ClFN5)2], the PtII atom, located on an inversion centre, is coordinated by the purine N atoms of the 2-chloro-6-[(3-fluoro­benz­yl)amino]-9-isopropyl-9H-purine ligands and two Cl atoms in a slightly distorted trans-square-planar coordination geometry [N—Pt—Cl angles = 89.91 (5) and 90.09 (5)°]. Weak intra­molecular N—H...Cl contacts occur. In the crystal, C—H...Cl and C—H...F contacts, as well as weak π–π stacking inter­actions [centroid–centroid distances = 3.5000 (11) and 3.6495 (12) Å] connect the mol­ecules into a three-dimensional architecture.

The title compound, [Pt(C6H6O4)(C12H8N2)]·2H2O, which crystallizes as two independent formula units, has the metal atom in a square-planar geometry defined by two O atoms of the chelating cyclo­butane-1,1-di­carboxyl­ate dianion and two N atoms of the chelating 1,10-phenanthroline mol­ecule (r.m.s. deviations of the PtO2N2 units = 0.026 and 0.026 Å). Adjacent complex and water mol­ecules are connected through inter­molecular O—H...O hydrogen bonds and C—H...O, C...O [shortest C...O distance = 3.140 (5) Å], π–π [shortest C...C distances = 3.234 (6) and 3.347 (6) Å] and Pt...π [shortest Pt...C distance = 3.358 (4) Å] inter­actions into a three-dimensional network.
