N2 - Diphenylphosphinic acid reacts with Mn2+ in the presence of dimethylformamide and two kinds of compounds are formed. Compound 1, {Mn[O2P(C6H5)2]2(DMF)}·DMF, consists of one-dimensional, infinite centrosymmetric chains of Mn(II) atoms connected by double phosphinate bridges. Each manganese atom is coordinated to four phosphinate oxygen atoms and one DMF molecule in a trigonal bipyramidal geometry with three equatorial angles of 123.7(6), 116.8(5) and 117.4(6)° and an axial- metal-axial angle of 173.3(7)°. The M...M separation is 4.583 Å. Compound 2, {Mn[O2P(C6H5)2]2 [HO2P(C6H5)2]2- (DMF)2} cocrystallizes with 1 under the same conditions. The manganese atom is coordinated to two phosphinate ions, to two phosphinic acid molecules and to two DMF molecules in an octahedral geometry. Two very strong, intramolecular hydrogen bonds are formed between the POH group of one ligand and the PO- group of another ligand with O...O separation of 2.444(3) Å. Compound 3 is the Co(II) analogue of 2, {Co[O2P(C6H5)2]2 [HO2P(C6H5)2]2(DMF)2}. The O...O separation in the intramolecular hydrogen bond in 3 is 2.422(4) Å. Compound 1: triclinic, space group P1 with a = 13.174(2), b = 13.364(2), c = 9.995(1) Å, α = 96.05(3), β = 110.23(3), γ = 104.54(2)°, V = 1562(1) Å3 and Z = 2. Compound 2: triclinic, space group P1 with a = 12.019(1), b = 12.390(1), c = 9.479(1) Å, α = 94.90(3), β = 101.71(2), γ = 102.65(3)°, V = 1336(1) Å3 and Z = 1. Compound 3: monoclinic, space group P21/c with a = 12.552(2), b = 9.921(1), c = 21.558(3) Å, β = 101.88(3)°, V = 2627(1) Å3 and Z = 2.
