We combine electronic coupled cluster (CCSD(T)) calculations with positronic multicomponent renormalized partialthird-order propagator (MC-REN-PP3) calculations to effectively recover correlation energies. Analysis of potential energy curves confirms the energetic stability of these positronicmolecules, with optimized structures identified as global minima. Further investigation of electron and positron densitiesreveals stabilization owing to the formation of two-positron bonds. The global stability of the Ps2XY complexes contrastswith the metastable two-positron-bonded (PsH)2, which energetically favors the emission of Ps2. Comparative analysis of one- and two-positron dihalides indicates that addinga positron to PsXY- generally results in shorter bond distances, higher force constants, and lower dissociation energies, with exceptions due to differences in positron affinities ofPsXY- and Y-. We explore the analogy between two-positron-bonded dihalide systems Ps2XY and two-electron-bonded dialkali molecules AB, (A,B=Na,K,Rb). The bonding properties in positron dihalides and their electronic dialkali analogs displayidentical periodic trends. However,compared to their isoelectronic AB counterparts, the positron bonds in Ps2XYhave shorter bond lengths, higher force constants, and higher bond energies.
