Abstract The quark-delocalization colour-screening model is employed to study the kaonic nuclear cluster K-pp system. The calculation shows that there is a strong effective attraction between kaon and protons. The bound state can be formed and the binding energy is estimated to be about 80MeV, and the space configuration is a symmetrical linear triatomic molecule with radius 1.15fm. The results also show that the quark delocalization is responsible for
the strong attraction in the system and the colour screening adds a little attraction in this case.
