In the cation of the title organic ion pair compound, C(23)H(20)ClN(2)O(3) (+)·CH(3)O(-), the cyclo-hexyl ring shows a half-boat conformation and the dihedral angles between two benzene rings and the pyran ring are 83.14 (7) and 73.18 (9)°. In the crystal, centrosymmetrically related cations are linked into a dimer by pairs of N-H⋯N hydrogen bonds, generating an R(2) (2)(12) ring motif. The ani...

Amino phosphonic acids are good heavy metal extractants for liquid–liquid extraction, but this method requires the use of an organic solvent, which is itself a pollutant. The incorporation these in solid supports gave us opportunity to find solution problem. synthesis new material by Amino-Cyclo-Hexyl Phosphonic Acid into interlayer space Ni/Al-LDH, designated as Ni/Al-ACHPA, was carried out co...

In the title thio-urea derivative, C(14)H(20)N(4)S, the non-ring non-H atoms are approximately planar, with an r.m.s. deviation of 0.0720 Å. The pyridine ring is twisted out of this plane and makes a dihedral angle of 16.85 (13)° with it. The mean plane passing through the cyclo-hexyl ring is almost normal to the central plane [dihedral angle = 69.23 (8)°]. An intra-molecular N-H⋯N(imine) hydro...

The structure of the title sulfonamide, C(12)H(15)Cl(2)NO(2)S, features a distorted tetra-hedral geometry for the S atom [maximum deviation: O-S-O = 120.23 (14)°]. One of the sulfonamide O atoms is coplanar with the benzene ring [C-C-S-O torsion angle = -174.5 (2)°], whereas the other lies well above the plane [C-C-S-O = 57.0 (3)°]. A chair conformation is found for the cyclo-hexyl ring. In the...

The title compound, [Hg2Cl4(C26H54B10P2)], was synthesized by the reaction of 1,2-bis-(di-cyclo-hexyl-phosphan-yl)-1,2-dicarba-closo-dodeca-borane with HgCl2. Both Hg(II) atoms show a distorted tetra-hedral coordination geometry, provided by the two bridging chloride anions and the P atoms of the diphosphanyl ligand for one metal atom, and by two bridging and two terminal chloride anions for th...

In the title compound, C9H13N3O, the cyclo-hexyl-idene ring adopts a chair conformation and the bond-angle sum at the C atom linked to the N atom is 359.6°. The cyano-acetohydrazide grouping is close to planar (r.m.s. deviation for the non-H atoms = 0.031 Å) and subtends a dihedral angle of 64.08 (4)° with the four C atoms forming the seat of the chair. The C=O and N-H groups are in a syn confo...

The structure of the title thio-urea derivative, C(14)H(16)N(4)O(5)S, features an almost planar central C(2)N(2)OS fragment (r.m.s. deviation = 0.005 Å), an arrangement stabilized by an intra-molecular N-H⋯O hydrogen bond. The terminal rings are twisted out of this plane, the dihedral angle formed with the benzene ring being 33.22 (10)°. The cyclo-hexyl ring is disordered, with two orientations...

The title compound, C32H35NO4, is an unexpected product obtained in the SmI2-mediated radical cross-coupling of a lactam 2-pyridyl sulfone with an arone. The asymmetric unit contains two mol-ecules. In both mol-ecules, the core pyrrolidinone ring adopts an approximate envelope conformation (with the C atom bearling the benzyloxy substituent as the flap) and the cyclo-hexyl ring has a chair conf...

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...

The crystal structure of the title compound {systematic name: (S)-(+)-N-[1-(2-chloro-phen-yl)-2-oxocyclo-hexyl]meth-anam-in-ium chloride}, C(13)H(17)ClNO(+)·Cl(-), was determined at 90 (2) K. The (S)-(+)-ketamine hydro-chloride salt is a well known anesthetic compound and is dramatically more potent than its R isomer. In the title compound, the cyclo-hexa-none ring adopts a chair conformation w...
