   Three new polynuclear clusters with the formulae [Mn₁₀O₄(OH)(OMe){(py)₂C(O)₂}₂{(py)₂C(OMe)(O)}₄(MeCO₂)₆](ClO₄)₂(1), Na[Mn₁₂O₂(OH)₃(OMe){(py)₂C(O)₂}₆{(py)₂C(OH)(O)}₂(MeCO₂)₂(H₂O)₁₀](ClO₄)₈(2) and [Mn₁₂O₄(OH)₂{(py)₂C(O)₂}₆{(py)₂C(OMe)(O)}(MeCO₂)₃(NO₃)₃(H₂O)(DMF)₂](NO₃)₂(3) were prepared from the combination of di‐2‐pyridyl ketone, (py)₂CO, with the aliphatic diols (1,3‐propanediol (pdH₂) or 1,4‐butanediol (1,4‐bdH₂)) in Mn carboxylate chemistry. The reported compounds do not include the aliphatic diols employed in this reaction scheme; however, their use is essential for the formation of1–3. The crystal structures of1–3are based on multilayer cores which, to our knowledge, are reported for the first time in Mn cluster chemistry. Direct current (dc) magnetic susceptibility studies showed the presence of dominant antiferromagnetic exchange interactions within1–3. Alternating current (ac) magnetic susceptibility studies revealed the presence of out‐of‐phase signals below 3.0 K for2and3indicating the slow relaxation of the magnetization vector, characteristic of single‐molecule magnets; theU_effvalue of2was found to be 23 K and the preexponential factorτ₀~7.6×10⁻⁹ s.

   Addition of the potassium dichalcogenidodiphenylphosphinate salts, KE₂PPh₂(E=S, Se), to either the THF solvate of vanadium(III) chloride or unsolvated chromium(III) chloride results in rapid ligand substitution and the formation of a series of closely‐related trivalent, neutral mononuclear complexes, M(E₂PPh₂)₃(M=V, Cr; E=S, Se), isolated in modest to good yield. The metal dichalcogenidophosphinate complexes reported herein were characterized by IR, UV‐vis, and¹H NMR spectroscopies, and their solid‐state molecular structures were determined by single‐crystal X‐ray crystallography. Importantly, the comparative analysis includes the structural and spectroscopic studies of two rare V(III) dithio‐ and diseleno‐phosphinate VE₆cores, as well as, two previously known CrE₆analogues. In the solid‐state the title complexes exhibit trigonal distortion from octahedral with torsion angles ranging from 43(2) to 50.3(6)° and structural parameters consistent with ligation of progressively ‘softer’ chalcogen‐donors.
