N,N′-Diphenylbut-2-enediamide
In the title compound, C(16)H(14)N(2)O(2), the conformations of the N-H and C=O bonds in the C-NH-CO-CH =CH-CO-NH-C segment are anti to each other. The two C=O bonds are also anti to each other. The two phenyl rings make an inter-planar angle of 41.2 (1)°. An intra-molecular N-H⋯O hydrogen bond occurs. In the crystal, inter-molecular N-H⋯O hydrogen bonding links the mol-ecules into infinite cha...

متن کاملMagneto-structural correlations in dinuclear Mn(III) compounds with formula [{Mn(L)(NN)}(μ-O)(μ-2-RC6H4COO)2{Mn(L')(NN)}]n+.
Three dinuclear Mn(III) compounds with oxo and carboxylato bridges have been synthesized and characterized by X-ray diffraction: [{Mn(L)(NN)}(μ-2-ClC(6)H(4)COO)(2)(μ-O){Mn(L')(NN)}](n+) with NN = 2,2'-bipyridine (1 and 2) or 1,10-phenanthroline (3). The counteranion is either NO(3)(-) (1 and 3) or ClO(4)(-) (2) and the monodentate positions (L, L') could be occupied by molecules of water or the...
متن کاملFast k-NN search
Random projection trees have proven to be effective for approximate nearest neighbor searches in high dimensional spaces where conventional methods are not applicable due to excessive usage of memory and computational time. We show that building multiple trees on the same data can improve the performance even further, without significantly increasing the total computational cost of queries when...
متن کاملnN Backward Scattering
nN backward scattering data above 5 GeV /c are analyzed in terms of the baryon Regge pole exchange and accompanying Regge cut due to the strong absorption. The fit of the cross sections is reasonable. The role of the cut turns out to be very important: (1) The extrapolated magnitude of the L10 residue at a 4 =! is significantly larger than that without the cut. Ll0 residue with or without the w...
