Popis:	The structurcs of two Pt(II) complexes cis -[Cl 2 Pt- (9-EtGH 2 ) 2 ]Cl 2 ·2H 2 O (2) and cis -[(pra) 2 Pt(9- EtGH) 2 ](NO 3 ) 2 (3) with 9-EtGH2  9-ethylguaninium cation, 9-EtGH  neutral 9-ethylguanine and pra  n-propylamine, are reported. Pt binding in both compounds is through N7 of the purine rings which in the case of 2 are protonated at N3. The guanines adopt head—tail orientations both in 2 and 3. The compounds crystallize in the space group P 2 1 / c with the following cell dimensions: a = 14.214(3) (2), 7.990(4) (3), b = 12.197(3) (2), 38.292(6) (3), c = 15.525(3) (2), 10.271(4) (3) A, β = 114.59(3) (2), 103.67(5)° (3), Z = 4.
