N,P,P-Triisopropyl­phosphinic amide

The title compound, C9H22NOP, was obtained by slow diffusion of oxygen into a toluene solution of iPr2PNHiPr. In the crystal, an inter­molecular N—H⋯O hydrogen bond occurs

1-Di­phenyl­phosphanyl-2-(di­phenyl­phosphor­yl)hydrazine

The title compound, C24H22N2OP2, is an asymmetrically substituted hydrazine derivative bearing a phosphoryl and a phosphanyl substituent. The PNNP backbone has a torsion angle of −131.01 (8)°. In the crystal, mol­ecules form centrosymmetric dimers by inter­molecular N—H...O hydrogen bonds, which are further linked into a three-dimensional network by weak C—H...O and C—H...π inter­actions

P-[N-(Diphenyl­phospho­rothio­yl)iso­propyl­amino]-N-isopropyl-P-phenyl­thio­phosphinic amide

The title compound, C24H30N2P2S2, was obtained by the reaction of Ph2PN(iPr)P(Ph)N(iPr)H with elemental sulfur in tetra­hydro­furan. In the solid state, intra­molecular N—H⋯S hydrogen bonding influences the mol­ecular conformation; a P—N—P—N torsion angle of 2.28 (9)° is observed. The two phenyl rings attached to one P atom form a dihedral angle of 74.02 (4)°

Donath-landsteiner hemolytic anemia with erythrophagocytosis and platelet phagocytosis in peripheral smear: Rare findings

The Donath-Landsteiner (DL) hemolytic anemia or paroxysmal cold hemoglobinuria (PCH) is a rare subtype of autoimmune hemolytic anemia (AIHA). We report here a case of a 22-year-old young female who presented with acute onset shortness of breath. Routine hematological investigation revealed erythrophagocytosis and platelet phagocytosis by monocytes in peripheral blood smear, which are rarely reported in AIHA, especially the DL. The unusual blood smear findings directed the pathologists to initiate workup for hemolytic anemia that yielded positive results in direct Coombs test C3d (Complement) and direct DL test. The findings confirmed the case as DL hemolytic anemia. To the best of our knowledge, this is the first report of both erythrophagocytosis and platelet phagocytosis in peripheral blood smear in PCH

Dichlorido[1,1-(diphenylphosphino)hydrazide]palladium(II) dichloromethane monosolvate

In the title compound, [PdCl2(C24H22N2P2)]·CH2Cl2, the palladium(II) atom is surrounded by a chelating P—N—P ligand Ph2P—N(NH2)—PPh2 containing a hydrazine entity and two chlorido ligands in a distorted square-planar coordination geometry. Beside the complex molecule, the asymmetric unit contains a co-crystallized dichloromethane molecule. The contributions of further disordered solvent molecules were removed from the diffraction data using the SQUEEZE [Spek (2015). Acta Cryst. C71, 9–18] procedure

1,1-Bis(diphenylphosphoryl)hydrazine

The title compound, C24H22N2O2P2, contains a diphosphazane backbone, as well as a hydrazine entity. The P—N—P diphosphazane unit and the N-amine N atom are almost coplanar, and the O atoms of the Ph2P(O) units are oriented trans to each other with respect to the P...P axis. In the crystal, centrosymmetrically related molecules are linked into dimers by pairs of N—H...O hydrogen bonds, forming rings of graph-set motif R22(10)

1,1,2,2-Tetraphenyl-1λ5-diphosphane 1-sulfide

In the title molecule, C24H20P2S, the P—P bond length is 2.2263 (5) Å. The two phenyl rings attached to the three- and five-coordinated P atoms, respectively, form dihedral angles of 56.22 (5) and 71.74 (5)°
