The D-dimensional Schrodinger equation with generalized Cornell potential (GCP) is transformed into a form that is compatible with extended Nikiforov–Uvarov (ENU) method, and its approximate solutions are obtained using this formalism. The energy spectrum for the GCP is obtained in closed form, and the wave function is determined using the biconfluent Heun differential equation. Some numerical results are shown to illustrate the behaviour of the bound state energies at different quantum states for various dimensions and selected diatomic molecular systems. In addition, the thermodynamic property expressions for GCP are obtained in closed form, and their variation with temperature is discussed extensively for various dimensions and selected diatomic molecular systems. In addition, the mass spectra of GCP and their special cases are studied for heavy mesons. Our results agree with those obtained in the literature.
