Version 5.39 with 4 updates (up to August 2018) of CSD was used for selection of organic crystals containing H(D), B, C, N, O, F, Si, P, S, Cl, As, Se, Br and I atoms. Disordered, erroneous, polymeric, pressurized, powder structures and experiments with R-factor > 0.075 were removed from consideration. 224 001 selected crystals were used for search of unique intermolecular contacts A•••B with distance D(A•••B) up to 7.0 Å. C-H, N-H and O-H bond lengths were normalized to CCDC/ConQuest defaults: C-H: 1.089 Å, N-H: 1.015 Å, O-H: 0.993 Å. Acetylenic Csp-H bond lengths were normalized to 1.06 Å (neutron diffraction: ACETYL05, RALDEN01, XEHLEB, ZULDEP01), and S-H bond lengths were normalized to 1.34 Å (microwave data: H2S, neutron diffraction: NALCYS02). For each contact the following information were collected: (1) contact geometry, (2) chemical nature of contact atoms, (3) shielding atom, and (4) contact shielding value. A total of c.a. 640 000 000 contacts were found, more than 40 000 000 of which was LoS depending on used vdW radii (41 346 551 for the final version from Table ). These data were used further to build and analyze the distribution of distances of various contacts and is available for download. Obtained line-of-sight A•••B contacts were used to plot histograms of contact distance distributions for all possible A, B atom type pairs (Table ). Primary analysis of these distributions combined with chemical common sense allowed to select atom types and, therefore, contacts used for the van der Waals radii determination. The main requirements were:
