The crystal structure of the title compound, (C(10)H(9)N(2))(2)[Mn(2)(C(10)H(8)N(2))(3)(H(2)O)(8)](C(8)H(3)O(7)S)(2)·C(10)H(8)N(2)·15H(2)O, consists of dinuclear Mn(II) complex cations, sulfonato-benzene-dicarboxyl-ate trianions, 4-(4-pyridyl)pyridinium cations, uncoordin-ated 4,4'-bipyridine and uncoordinated water mol-ecules. One 4,4'-bipyridine mol-ecule bridges two Mn atoms, forming a centr...

Understanding the formation of metal-molecule contact at microscopic level is key towards controlling and manipulating atomic-scale devices. Employing two isomers bipyridine, $4,{4}^{\ensuremath{'}}$ bipyridine $2,{2}^{\ensuremath{'}}$ between gold electrodes, here, we investigate a bond by studying charge transport through single molecular junctions using mechanically controlled break junction...

Reaction of enaminones 1a-d with 2-aminoprop-1-ene-1,1,3-tricarbonitrile (2) in the presence of AcOH/NH₄OAc afforded 7-amino-5-oxo-5,6-dihydro-1,6-naphthyridine-8-carbonitrile derivatives 9a-d. On the other hand, 2-aminopyrano[4,3,2-de] [1,6]naphthyridine-3-carbonitriles 20a-c,e were the only obtained products from the reactions of 1a-d with 2 in the presence of AcOH/NaOAc, while 1d afforded [3...

The asymmetric unit of title compound, [Cu(NCS)(C(10)H(8)N(2))(2)]ClO(4), contains a bis-(2,2'-bipyridine)(isothio-cyanato)copper(II) cation and a perchlorate anion. In the cation, the Cu(2+) ion is coordinated by four N atoms from two bidentate 2,2'-bipyridine mol-ecules and an N atom from an isothio-cyanate anion, resulting in a distorted CuN(5) pyramidal configuration. The crystal structure ...

A catalyst-free synthetic strategy to chromene carbonitriles by Multi-Component Reaction of pyrazole aldehydes, 5,5-dimethylcyclohexane-1,3-dione and malononitrile with ethanol, at room temperature is reported. Screening solvents purification the compounds were also performed. The newly synthesized novel compound’s (4H-chromene-3-carbonitriles) structures authenticated spectral techniques viz. ...

A series of novel pyrazole amide derivatives 3a-3p which take TMV PC protein as the target has been designed and synthesized by the reactions of 5-chloro-1-aryl-3-methyl-1H-pyrazole-4-carboxylic acids with 5-amino-1-aryl-1H-pyrazole-4-carbonitriles. All the compounds were characterized by 1H-NMR, mass spectroscopy and elemental analysis. Preliminary bioassays indicated that all the compounds ac...
