New pyrimido [4, 5-e] [1, 3, 4]thia- diazin-7-yl] hydrazines were synthesized via the cyclocondensation of alkyl-2-phenylhydrazinecarbodithioates as a binucleophile with 5-bromo-2,4-dichloro-6-methylpyrimidine as a bielectrophile , and replacement of C-7 chloro atom by hydrazine in ethanol as the solvent . This method has advantages over methods currently described in the literature for the con...

The structure of the 1:1 proton-transfer compound of 4-chloro-aniline with 4,5-dichloro-phthalic acid (DCPA), viz. C(6)H(7)ClN(+)·C(8)H(3)Cl(2)O(4) (-), has been determined at 130 K. The non-planar hydrogen phthalate anions and the 4-chloro-anilinium cations form two-dimensional O-H⋯O and N-H⋯O hydrogen-bonded substructures which have no peripheral extension. Between the sheets there are weak π...

In the title compound, [Co(C(7)H(3)Cl(2)O(2))(2)(C(10)H(8)N(2))(CH(3)OH)(2)](n), the Co(II) ion lies on a twofold rotation axis and is in a slightly distorted octa-hedral CdO(4)N(2) environment, formed by two O atoms from monodentate dichloro-benzoate ligands, two O atoms from methanol ligands, and two N atoms from trans-related 4,4'-bipyridine ligands. The bipyridine ligands also lies on a two...

The asymmetric unit of the title triangulo-triruthenium compound, 2[Ru(3)(C(21)H(21)AsO(3))(C(25)H(22)P(2))(CO)(9)]·CH(2)Cl(2), contains one triangulo-triruthenium complex mol-ecule and one half-mol-ecule of the dichloro-methane solvent. The dichloro-methane solvent lies across a crystallographic inversion center leading to the mol-ecule being disordered over two positions of equal occupancy. T...

Reaction of [Pd(PPh(3))(4)] with 1,1-dichloro-2,3-diarylcyclopropenes gives complexes of the type cis-[PdCl(2)(PPh(3))(C(3)(Ar)(2))] (Ar = Ph 5, Mes 6). Reaction of [Pd(dba)(2)] with 1,1-dichloro-2,3-diarylcyclopropenes in benzene gave the corresponding binuclear palladium complexes trans-[PdCl(2)(C(3)(Ar)(2))](2) (Ar = Ph 7, p-(OMe)C(6)H(4)8, p-(F)C(6)H(4)9). Alternatively, when the reactions ...

25 Regions selective for faces, places, and bodies feature prominently in the literature on 26 the human ventral visual pathway. Are selectivities for these categories in fact the most 27 robust response profiles in this pathway, or is their prominence an artifact of biased 28 sampling of the hypothesis space in prior work? Here we use a data-driven structure 29 discovery method that avoids the...
