The tmQM dataset provides the quantum properties, including geometries and atomic charges, of 86k transition metal complexes (TMCs) representing the 3d, 4d, and 5d series. Structures were extracted from the Cambridge Structural Database (CSD) with a series of filters, yielding single-metal species with charges in the range [-1, 0, 1]. tmQM contains organometallic, bioinorganic, and Werner complexes. All properties were computed for the closed-shell singlet state. The dataset is distributed in the four files provided below, in which all TMCs are labeled with their CSD code. Further details can be found in the article The tmQM Dataset - Quantum Geometries and Properties of 86k Transition Metal Complexes.
