The structure of [H2B(3,5-Me2pz)2]2Cd shows the four nitrogen donor atoms form a pseudotetrahedral arrangement about the cadmium(II). The intraligand N—Cd—N angles are restricted to an average of 91.4° by the chelate rings forcing the interligand N—Cd—N bond angles to average 119.4°. The Cd—N bond distances average 2.21 Å with a range of 0.04 Å. The crystal is in the triclinic space group, P
with a = 7.6793(2) Å, b = 8.5992(2) Å, c = 25.0874(4) Å, = 91.0791(2)°, = 97.9769(4)°, = 110.2344(6)°, and Z = 2. 相似文献

The copper complex, [Cu2(II)(dmpa)2(p-Cl-C6H5COO)2], has been prepared and its structure determined using X-ray crystallography. The dimer is a di-2-alkoxo complex which is a five-coordinate copper dimer with unsupported alkoxo bridges. The complex crystallizes in the triclinic space group P-1 with a = 11.384(2), b = 14.636(5), c = 9.609(2) Å, = 100.07(2), = 104.33(3), = 72.79(2)°, V = 1471.8(7) Å3, and Z = 2. The structure is comprised of discrete binuclear clusters in which the metal atoms are bridged by two alkoxo oxygens of the dmpa– ligands. The Cu-O and Cu-N distances are in good agreement with those found for other copper(II) aminoalcoholato complexes. The Cu···Cu distance is 2.9765(6) Å. In the crystal, every two dimeric coordination molecules are combined together by the recognition through intermolecular hydrogen-bonding interactions between the apical water molecule and the non-coordinated O atom from the p-chlorobenzoato ligand, forminga tetramer. 相似文献
The spectroscopic characterization (1H, 13C{1H} NMR, UV–Vis) and single-crystal X-ray diffraction (scXRD) analysis accomplished by inspection of the Hirshfeld surface of bis(3-thienoyl) disulfide (1) is described. The title compound 1 crystallizes in the monoclinic space group P21/n. The unit cell parameters are a?=?7.9959(3) Å, b?=?6.4348(3) Å, c?=?22.4924(9) Å, β?=?100.108(4)°, V?=?1139.32(8) Å3, Z?=?4, Rgt(F)?=?0.0278, wRref(F2)?=?0.0667. The packing of 1 is dominated by S?O and S?S interactions, giving a 2D layer structure parallel to (101). The X‐ray crystal structure analysis revealed the packing of 1 is dominated by S?O and S?S interactions, giving a 2D layer structure parallel to (101). The intermolecular interactions in 1 were analyzed using the Hirshfeld surface method including 2D fingerprint plots and enrichment ratios (E), which shows that the most favored intermolecular contacts are the O?H and C?S indicated by E values above 1.30. The interaction energies between molecular pairs revealed the importance of the weak O?H and C?S interactions in stabilizing the molecular structure of 1.

The title mixed-ligand copper(II) complex has been synthesized and its crystal structure at room temperature solved. The crystals are monoclinic:P21/c,a=12.004(3),b=19.402(5),c=14.192(4) Å,=108.80(3)°,Z=4. The structure was solved by direct methods, and refined to anR value of 0.041 for 4457 nonzero independent reflections. The crystal structure consists of discrete [Cu(bipy) (MPhP)] units, noncoordinated MPhPH2, and H2O molecules. Each [Cu(bipy)2(MPhP)] unit involves a five coordinate CuN4O chromophore with a distorted trigonal-bipyramidal stereochemistry. The phosphate groups are linked together by short hydrogen bonds of (P)-O-H--O-P type. 相似文献
4-Chlorobenzoic acid reacts with silver oxide and 1-(2-aminoethyl)piperidine to give a dinuclear silver(I) complex, [Ag2(C7H4ClO2)2(C7H16N2)2]. The complex was characterized by elemental analysis and X-ray diffraction. The complex crystallizes in the triclinic space group P−1 with unit cell dimensions a = 6.8550(10), b = 8.7370(10), c = 13.859(2) ?, α = 73.213(3), β = 87.945(3), γ = 77.050(3)°, V = 774.09(18) ?3, Z = 1, R1 = 0.0386, and wR2 = 0.0791. The dimeric Ag complex is located on an inversion center. The Ag atom in the complex is three-coordinated by two N atoms from two 1-(2-aminoethyl)piperidine ligands and by one O atom of a 4-chlorobenzoate ligand, forming a triangular coordination. In the crystal structure, the molecules are linked through intermolecular N–H···O hydrogen bonds, forming chains running along the a axis. The complex shows high cytotoxic property to both normal and carcinoma cells. 相似文献

The title compound, C9H10O2S, (I), crystallizes in the triclinic space group, P − 1, with unit cell parameters a = 6.2249(3), b = 7.3733(5), c = 19.5708(12), Å, α = 86.746(5)°, β = 88.682(5)°, γ = 86.988(5)°, Z = 4. The molecule consists of a methyl sulfanyl group bonded to benzyl acetic acid at the 4 position crystallizing with two
molecules in the asymmetric unit. The carboxylic acid group from the acetic acid moiety in these two molecules forms a classic
O–H···O hydrogen bonded dimer with O···O distances of 2.673(2) and 2.646(2) Å, in a R22 (8) graph-set motif which link the molecules into pairs around inversion centers in the unit cell. The dihedral angles between
the mean planes of the R22 (8) graph-set motif with the mean planes of the two nearby benzyl groups within the same dimer in the unit cell are 64.1(6)°
and 71.3(4)°, respectively. Within the same dimer the dihedral angle between the two benzyl groups is 45.2(1)°. The structure
is supported by a weak intermolecular C–H···Cg π-ring interaction and gives support to molecular packing stability in the
unit cell. Comparison to a MOPAC AM1 computational calculation provides support to these observations. 相似文献
Abstract The crystal structure of the title compound, C64H70N4O4, has been determined by single crystal X-ray diffraction methods. The title compound crystallizes in the monoclinic space
group P2(1)/c with cell dimensions a = 13.8946(3) ?, b = 16.1069(3) ?, c = 12.1974(2) ?, β = 93.4050(10)°, Z = 2. The porphyrin core to be composed of four pyrrole rings linked through methane carbon bridges. Each molecule lies across
a crystallographic inversion center. The porphyrin core is planar, which facilitates π-electron delocalization. The inner
nitrogen H atoms are found localized on opposite pyrrole rings and these rings differ structurally from the other two pyrrole
rings. The imino H atoms form bifurcated intramolecular hydrogen bonds with the adjacent unprotonated N atoms due to the contract
porphyrin core.
