Single-crystal X-ray diffraction studies revealed the complexes to be {[(phen)2Ni]2(\u03bc-P2O7)}\u00b727H2O (1) and {[(phen)2Mn]2(\u03bc-P2O7)}\u00b713H2O (2) where the asymmetric M(phen)2 units are bridged by bis-bidentate pyrophosphate, each metal ion exhibiting a distorted octahedral geometry. The bridging pyrophosphate places adjacent metal centers at 5.031 \u00c5 in 1 and 4.700 \u00c5 in 2, and its conformation also gives rise to an intramolecular \u03c0\u2212\u03c0 interaction between two adjacent phen ligands. Intermolecular \u03c0\u2212\u03c0 interactions between phen ligands from adjacent dinuclear complexes create an ornate 3D network in 1, whereas a 2D sheet results in 2. The hydrophilic nature of the pyrophosphate ligand leads to heavy hydration with the potential solvent-accessible area for 1 and 2 accounting for 45.7% and 26.4% of their unit cell volumes, respectively. Variable-temperature magnetic susceptibility measurements on polycrystalline samples of 1 and 2 revealed net weak intramolecular antiferromagnetic coupling between metal centers in both compounds with J = \u22123.77 cm-1 in 1 and J = \u22120.88 cm-1 in 2, the Hamiltonian being defined as H = \u2212JSA\u00b7SB. The ability of the bis-bidentate pyrophosphate to mediate magnetic interactions between divalent first row transition metal ions is discussed bearing in mind the number and nature of the interacting magnetic orbitals.<\/jats:p>","DOI":"10.1021\/ic700439a","type":"journal-article","created":{"date-parts":[[2007,7,17]],"date-time":"2007-07-17T07:00:40Z","timestamp":1184655640000},"page":"6668-6674","source":"Crossref","is-referenced-by-count":40,"title":["Synthesis and Structural and Magnetic Characterization of\n{[(phen)2Ni]2(\u03bc-P2O7)}\u00b727H2O and {[(phen)2Mn]2(\u03bc-P2O7)}\u00b713H2O:\u2009 Rare\nExamples of Coordination Complexes with the Pyrophosphate Ligand"],"prefix":"10.1021","volume":"46","author":[{"given":"Oluwatayo F.","family":"Ikotun","sequence":"first","affiliation":[{"name":"Department of Chemistry, Syracuse University, Syracuse, New York 13244-4100, Department of Qu\u00edmica Inorg\u00e1nica\/Instituto de Ciencia Molecular, Universitat de Valencia, Pol\u00edgono La Coma s\/n, E-46980 Paterna, Valencia, Spain, Department of Chemistry, College of Science, University of Canterbury, Christchurch, 8020, New Zealand, and Chemistry Department, The Queen's University of Belfast, Belfast, U.K., BT9 5AG"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"N.
