چکیده
One of the tertiary amine atoms has been protonated in the title salt, C(36)H(57)N(4) (+)·NO(3) (-). The four N atoms of the macrocycle are almost coplanar (r.m.s. deviation = 0.0053 Å), a result correlated with the formation of intra-molecular N-H⋯N and N-H⋯(N,N) hydrogen bonds. With respect to this plane, the benzyl groups lie to either side; a similar arrangement pertains for the cyclo-hexyl rings (each with a chair conformation). Helical supra-molecular chains are evident in the crystal, whereby alternating cations and anions are linked by C-H⋯O inter-actions. The chains are consolidated into supra-molecular arrays in the ab plane via C-H⋯π contacts involving both benzene rings.

The Cu(II) atom in the title compound, [Cu(NO(3))(2)(C(20)H(40)N(4))], is N,N',N'',N'''-chelated by the macrocyclic ligand: the four N atoms form a square, above and below which are located the O atoms of the nitrate ions. The metal atom exists in a tetra-gonally distorted octa-hedron, on a special position of [Formula: see text] site symmetry. One of the amino groups is hydrogen bonded to an O...

In the title co-crystal, C(20)H(40)N(4)·2C(11)H(10)O, the macrocycle is generated by a crystallographic inversion centre. The N atoms show a pyramidal coordination, and the cyclo-hexane ring that is fused to the 14-membered C(10)N(4) ring exists in a chair conformation, whereas the methyl substituent occupies an axial site. The (naphthalen-1-yl)methanol mol-ecule forms an O-H⋯N hydrogen bond to...

The asymmetric unit of title hydrated salt, C22H46N4 (2+)·2Cl(-)·4H2O, comprises half a centrosymmetric dication, one Cl(-) anion and two water mol-ecules of crystallization. The structure determination reveals that protonation has occurred at diagonally opposite amine N atoms, and that the dication features intra-molecular N-H⋯N hydrogen bonds. In the crystal, a three-dimensional artchitecture...
متن کاملOxidation of Dibenzyl Sulfide via an Oxygen Transfer from Palladium Nitrate
Dibenzyl sulfide was oxidized at the α-carbon to yield benzaldehyde in the presence of Pd(NO3)2. Oxygen itself could not oxidize the sulfide directly, instead the nitrato ligand of the palladium complex transferred oxygen to dibenzyl sulfide to form benzaldehyde. The X-ray crystal structure of the intermediate complex, cis[Pd(NO3)2{S(CH2C6H5)2}2], revealed that the nitrato ligand was unidentate...

The asymmetric unit of the title compound, C(30)H(34)N(4)O(6), contains two independent mol-ecules. In one independent mol-ecule, the two eth-oxy-carbonyl groups are each disordered over two conformations with occupancy ratios of 0.586 (2):0.414 (2) and 0.508 (2):0.492 (2). The crystal packing exhibits weak inter-molecular C-H⋯O hydrogen bonds.
