The MnBr2 complex of N2,N6-bis-(di-tert-butyl-phosphan-yl)pyridine-2,6-di-amine (1·MnBr2) co-crystallizes with 5.69% of the monophosphine oxide analogue (1O·MnBr2) and two tetra-hydro-furan (THF) mol-ecules, namely [N2,N6-bis-(di-tert-butyl-phosphan-yl)pyridine-2,6-di-amine]-dibromido-manganese(II)-[bis-(di-tert-butyl-phosphan-yl)({6-[(di-tert-butyl-phosphan-yl)amino]-pyridin-2-yl}amino)-phosph...

Quaterpyridines have been demonstrated to be useful building blocks in metallo-supramolecular chemistry; however, their synthesis requires the preparation of sensitive building blocks. We present here three examples of nonsymmetric quaterpyridines that were easily obtained in yields of 70-85% by condensation of commercially available enones with 6-acetyl-2,2':6',2''-terpyridine through a Kröhnk...

In the title compound, the dihedral angles between the 2-amino-5-chloro-pyridyl rings and the pyridine ring are 56.26 (6)° and 78.83 (5)°; the angle between the 2-amino-5-chloro-pyridyl rings is 72.42 (5)°. The solvent water mol-ecules are linked to the organic compound by N-H⋯O, O-H⋯O, N-H⋯N and O-H⋯N hydrogen bonds. π⋯π Stacking inter-actions are also observed between the 2-amino-5-chloro-pyr...

The reaction of 4-methyl-2-phenyl-1,2-dihydro-6-oxo-5-pyridine- carbonitrile (1) with arylidene malononitrile afforded isoquinoline derivatives 2a,b. 6-Chloro-4-methyl-2-phenyl-5-pyridinecarbonitile (3) obtained by chlorination of compound 1 with phosphoryl chloride was converted into 6-amino-4-methyl-2-phenyl-5-pyridinecarbonitrile (4) and 6-hydrazido-4-methyl-2-phenyl-5-pyridinecarbonitrile (...

In the title complexes, trans-(2-amino-pyridine-κN)di-chlorido-{4-eth-oxy-carbonyl-meth-oxy-3-meth-oxy-1-[(2,3-η)-prop-2-en-1-yl]benzene}-platinum(II), [PtCl2(C5H6N2)(C14H18O4)], (I), and (2-amino-pyridine-κN)chlorido{5-eth-oxy-car-bon-yl-meth-oxy-4-meth-oxy-1-[(2,3-η)-prop-2-en-1-yl]phenyl-κC1}-platinum(II), [Pt(C14H17O4)Cl(C5H6N2)], (II), the central PtII metal atom displays a distorted squar...
