With many new quantum chemistry methods being developed recently, it is clearly critical that highly accurate, well-balanced, reference data for many different atomic and molecular properties be available for the parametrization and validation of these methods. Here, we present such a reference for noncovalent interaction in organic molecules. These are strongly influenced by correlation effects, it is necessary to use computationally expensive high-order wave function methods to describe them accurately, namely CCSD(T)/CBS. Data are presented for 66 molecular complexes, at their reference equilibrium geometries and at 8 points systematically exploring their dissociation curves. The data set was used to test several correlated QM methods, including those parametrized specifically for noncovalent interactions. Among these, the SCS-MI-CCSD method outperforms all other tested methods.
