The [Ni(DDM)2(NO3)2(H2O)2] complex (DDM is 4,4-diaminodiphenylmethane [CH2(C6H4NH2)2]) is synthesized, and its structure is determined. The crystals are triclinic, space group P
, a = 5.846(1) ?, b = 9.450(2) ?, c = 13.390(3) ?, α = 105.63(3)°, β = 98.13(3)°, γ = 105.84(3)°, V = 666.6(2) ?3, ρcalcd = 1.553 g/cm3, Z = 2. The Ni(II) ion (in the inversion center) is bound to a distorted octahedral array formed by the nitrogen atoms of the
primary amino groups of the DDM molecules and the oxygen atoms of the monodentate nitrato groups and water molecules (Ni(1)-N(3)
2.119(2) ?, Ni(1)-O(1) 2.122(2) ?, Ni(1)-O(w) 2.047(2) ?, angles at the Ni atoms vary in the 85.08(9)°–94.92(9)° interval).
The structure contains supramolecular metallacycles formed by the O(w)-H…N(2) hydrogen bonds between the coordinated H2O molecules and the terminal amino groups of DDM. The metallacycles are joined by the Ni2+ ions into infinite chains running in the [111] direction.

A new binuclear cadmium(II) complex with neutral ligands, 1,2-diaminobenzene (DMB) and dimethylformamide (DMF), [Cd2(Ph(NH2)2)5(DMFA)4](B10H10)2, was synthesized and studied by IR spectroscopy and X-ray diffraction. The crystals are monoclinic, a = 26.198(3) ?, b = 12.742(3) ?, c = 21.658(3) ?, β = 119.985(10)°, Z = 8, space group C2/c. The distorted octahedral environment of Cd is formed by four nitrogen atoms of three DAB molecules and two oxygen atoms
of DMF molecules. Three independent DAB molecules perform different functions: one chelates the Cd atom, another is linked
to cadmium as a monodentate ligand, and the third one bridges two Cd atoms, thus forming the dimer. The amino groups of the
DAB molecules are involved in the N-H⋯O and N-H⋯N hydrogen bonds and in N-H⋯B and N-H⋯H-B specific interactions with the cluster
boron anion.

1-Allyl-4-aminopyridinium chloride reacts with Cu(NO3)2 · 3H2O in an ethanolic solution under the conditions of ac electrochemical synthesis at copper electrodes to form crystals of compound
[(NH2C5H4N(C3H5))2Cu3Cl3(NO3)2] (I). The crystals of compound I are monoclinic: space group P21/c, Z = 4, a = 25.770(7), b = 7.230(4), c = 12.505(5) ?, β = 92.58(3)°, V = 2328(2) ?3. The direct interaction of 1-allylquinolinium nitrate with Cu(NO3)2 · 3H2O in a methanolic solution in the presence of metallic copper yields crystals of compound [C9H7N(C3H5)Cu(NO3)2] (II).

. Each of two copper atoms (Cu(1) and Cu(2)) π-coordinates the C=C bonds of the allyl groups of the 1-allyl-4-aminopyridinium
cations, the oxygen atom of the nitrate ions, and two chlorine atoms. The third copper atom Cu(3) is linearly linked with
two chlorine atoms. Particular polymeric fragments are additionally joined by the N-H…O, C-H…O, C-H…Cl hydrogen bonds. The
crystal structure of compound II is built-up of the isolated L2Cu2(NO3)4 fragments (L is the 1-allylquinolinium cation). The metal atom is localized in the trigonal pyramidal coordination environment
of three oxygen atoms of the nitrate ions and of the C=C bond of the allyl group of the cation. The particular L2Cu2(NO3)4 fragments are additionally joined by the C-H…O hydrogen bonds.

1,2-Eliminations are a varied and extensive set of dissociations of ions in the gas phase. To understand better such dissociations,
elimination of CH2=CH2 and CH3CH3 from (CH3)2NH+CH2CH3 (1) and of CH4 from (CH3)2NH2+ are characterized by quantum chemical calculations. Stretching of the CN bond to ethyl is followed by shift of an H from
methyl to the bridging position in ethyl and then to N to reach (CH3)2NH2+ + CH2=CH2 from 1. CH3CH3 elimination by H-transfer to C2H5+ to form CH3NH+=CH2 + CH3CH3 also takes place. (CH3)2NH2+ eliminates methane by CN bond extension followed by β-H-transfer to give CH2=NH+ + CH4. Low-energy reactions resembling complex-mediated 1,2-eliminations occur and constitute a hitherto largely unrecognized type
of reaction. As in many complex-mediated reactions, these reactions transfer H between incipient fragments. They are distinguished
from complex-mediated processes by the fragments not being able to rotate freely relative to each other near the transition
state for reaction, as they do in complexes. Most 1,2-eliminations are ion-neutral complex-mediated, occur by the just described
lower energy reactions, have 1,1-like transition states, or utilize highly asynchronous 1,2 transition states. All of these
avoid synchronized 1,2-transition states that would violate conservation of orbital symmetry. 相似文献

Single crystals of [CuCl0.85Br0.15(C6H4N3CH2=CH2)] (I) were obtained by alternating current electrochemical synthesis; their X-ray structural investigation has been carried
out (DARCh automatic diffractometer, MoK
α radiation, θ/2θ scanning; 1460 reflections with F ≥ 4σ(F), R = 0.0517). The crystals are monoclinic, their space group is P21/c, a = 7.292(3) Å, b = 17.947(8) Å, c = 7.398(4) Å, β = 93.56(4)°, V = 966(1) Å3, Z = 4). Complex I is close in structure to the previously investigated compound [CuCl(C6H4N3CH2=CH2)] (II). In both structures, the trigonal-pyramidal surroundings of the copper atom include two halide atoms (one is apical),
a nitrogen atom, and a C=C group. The Cu2X2 dimers are associated into {[Cu2X2(C6H5N3CH2=CH2)]}n layers due to the bridging function of the 1-allylbenzotriazole molecule. In spite of the similar coordination polyhedra
of the metal atoms and identical bridging function of the ligand molecule in I and II, the differences in the conformation
parameters of the allyl group π-coordinated by the copper(I) atom (trans-like in I and cis-like in II) caused by the presence
of bromine atoms in the coordination sphere predetermine different structures of the organometallic [Cu2X2(C6H5N3CH2=CH2)]4 tetramer subunits in the layers and, as a consequence, formation of different crystal structures.

Its structure was determined from single-crystal X-ray diffraction at room temperature with final R=0.0774 and Rw=0.0893. It crystallizes in the monoclinic system (space group P21/n with a=9.74(2) Å, b=6.776(5) Å, c=12.60(2) Å, β=96.1(1)°, V=827(2) Å3 and Z=2). This compound contains mixed-valence V5+/V4+ vanadium oxide layers built from [VVO4] tetrahedra and pairs of edge-sharing [VIVO5] square pyramids with protonated organic amines occupying the interlayer space. 相似文献
