We study the possibility of binding eight quarks in a molecular hadronic system composed of two nucleons and an antikaon, with the quantum numbers of a hexaquark flavor, in particular, with strangeness \ensuremath-1, isospin 1/2, parity -, baryonic number 2, and two possible spins, 0 or 1. We discuss the possible production of this hadron in the experiments which are presently investigating hot topics like the \ensuremathΘ+ pentaquark or the K^\ensuremath- deeply bound in nuclei. The K^\ensuremath-\ifmmode\bullet\else\textbullet\fiN interactions and the coupling to other channels are computed microscopically from a confining and chiral invariant quark model resulting in local plus separable Gaussian potentials. The N\ifmmode\bullet\else\textbullet\fiN interactions used here are the state of the art Nijmegen potentials. The binding energy and the decay rate of the K^\ensuremath-\ifmmode\bullet\else\textbullet\fiN and K^\ensuremath-\ifmmode\bullet\else\textbullet\fiN\ifmmode\bullet\else\textbullet\fiN systems are computed with configuration space variational methods.
