The reaction of (NBu(n)(4))[Mn(8)O(6)Cl(6)(O(2)CPh)(7)(H(2)O)(2)] (1) with 2-(hydroxymethyl)pyridine (hmpH) or 2-(hydroxyethyl)pyridine (hepH) gives the Mn(II)(2)Mn(III)(10) title compounds [Mn(12)O(8)Cl(4)(O(2)CPh)(8)(hmp)(6)] (2) and [Mn(12)O(8)Cl(4)(O(2)CPh)(8)(hep)(6)] (3), respectively, with X = Cl. Subsequent reaction of 3 with HBr affords the Br(-) analogue [Mn(12)O(8)Br(4)(O(2)CPh)(8)(h...

Idiopathic membranous nephropathy (IMN) is known to be associated with antibodies acting on the M-type phospholipase A2 receptor (PLA2R) of the podocyte. However, the mechanism underlying de novo membranous nephropathy (dn MN) posttransplantation remains unclear. In this study, we aimed to elucidate the mechanism underlying dn MN.We selected 8 cases with dn MN and compared them to 20 IMN cases....

The structure of the title compound octa-kis-{[4-(dimethyl-amino)-pyridine](nitros-yl)[N,N'-(o-phenyl-ene)bis-(pyridine-2-carboxamidato)]manganese(II)} ethanol hepta-solvate 3.5-hydrate, [Mn(C(18)H(12)N(4)O(2))(C(7)H(10)N(2))(NO)](8)·7C(2)H(5)OH·3.5H(2)O, or 8[Mn(bpb)(DMAP)(NO)]·7EtOH·3.5H(2)O, is an unusual example of a structure with Z' = 8. The tetra-dentate bpb ligand, together with the nit...

BACKGROUND Manganese (Mn) is a naturally occurring element and an essential nutrient for humans and animals. However, exposure to high levels of Mn may cause neurotoxic effects. The pathological mechanisms associated with Mn neurotoxicity are poorly understood, but several reports have established it is mediated, at least in part, by oxidative stress. OBJECTIVES The present study was undertak...

This study explored the feasibility of localized manganese-enhanced MRI (MEMRI) via 3 different routes of Mn administrations for visuotopic brain mapping of retinal, callosal, cortico-subcortical, transsynaptic and horizontal connections in normal adult rats. Upon fractionated intravitreal Mn injection, Mn enhancements were observed in the contralateral superior colliculus (SC) and lateral geni...

The title compound, (C(8)H(20)N)[Mn(2)(C(6)H(5)O)(3)(CO)(6)], was synthesized from [Mn(CO)(3)(CH(3)CN)(3)]BF(4) and (C(8)H(20)N)(OC(6)H(5)). The binuclear anion exhibits a pseudo-threefold symmetry and contains two six-coordinate Mn atoms. Each metal atom is coordinated by three facially oriented CO ligands and three doubly-bridging phenolate ligands. The average O-Mn-O bond angle is 74.9 (7)° ...

Ligand modification transforms a polyoxometalate-anchored cubane-type [Mn(III)(3)Mn(IV)O(4)] core into a centrosymmetric [Mn(III)(6)Mn(IV)O(8)] di-cubane cluster, and restores the slow magnetization relaxation characteristics typical for [Mn(4)O(4)] cubane-based single-molecule magnets.

The asymmetric unit of the title Mn(II) coordination polymer, {[Mn(2)(C(8)H(6)O(8))(H(2)O)(3)]·H(2)O}(n), contains two crystallographic-ally independent Mn(II) cations, two half butane-1,2,3,4-tetra-carboxyl-ato anions, each lying on a centre of inversion, and four water mol-ecules. The Mn(II) cation has a distorted octa-hedral coordination environment. One Mn centre is coordinated by four carb...
