(Z)-2-Phenyl-3-pivaloyl-1,1-dipropyl-guanidine.

ABSTRACT: In the title compound, C(18)H(29)N(3)O, a polysubstituted guanidine, the torsion angles indicate that the guanidine unit and the carbonyl group are almost perpendicular to one another [O-C-N-C= -7.40 (18), C-N-C-N= -97.21 (15) and 86.41 (13)°]. The crystal packing is stablized by inter-molecular N-H⋯O hydrogen bonds, which link the mol-ecules into a chain.

2-Benzoyl-1,1-diethyl-3-phenyl-guanidine.

Project description:In the title tetrasubstituted guanidine, C(18)H(21)N(3)O, the guanidine and carbonyl groups are not coplanar, as reflected by the torsion angles involving the N=C atoms [17.6?(3), -141.68?(17) and 42.2?(3)°]. This is probably due to the absence of an intra-molecular N-H?O hydrogen bond, forming a six-membered ring, and is commonly observed in this class of compounds. In the crystal structure, centrosymmetric dimers are formed via pairs of inter-molecular N-H?O hydrogen bonds. The dihedral angles between the guanidine plane and the phenyl ring and benzoyl plane are38.06?(9) and 41.54?(7)°, respectively.

Guanidinium phenyl-arsonate-guanidine-water (1/1/2).

Project description:In the structure of the title compound, CH(6)N(3) (+)·C(6)H(6)AsO(3) (-)·CH(5)N(3)·2H(2)O, the phenyl-arsonate anion participates in two R(2) (2)(8) cyclic hydrogen-bonding inter-actions, one with a guanidinium cation, the other with a guanidine mol-ecule. The anions are also bridged by the water mol-ecules, one of which completes a cyclic R(5) (3)(9) hydrogen-bonding association with the guanidinum cation, conjoint with one of the three R(2) (2)(8) associations about that ion, as well as forming an R(2) (1)(6) cyclic association with the guanidine mol-ecule. The result is a three-dimensional framework structure.

2-Benzoyl-1-(2,4-dichloro-phen-yl)-3-phenyl-guanidine.

Project description:In the title compound, C(20)H(15)Cl(2)N(3)O, a typical polysubstituted guanidine with normal geometric parameters, the torsion angles [C-N-C-O = 3.8?(2), N-C-N-C = -6.1?(2)°] indicate that the guanidine and carbonyl groups are almost coplanar, due to the pseudo-hexa-gonal ring formed by intra-molecular N-H?O hydrogen bonds. The crystal packing is stabilized by inter-molecular N-H?O hydrogen bonds, which link the mol-ecules into centrosymmetric dimers.

1,1'-(p-Phenyl-enedimethyl-ene)dipiperidin-4-one.

Project description:In the mol-ecule of the title compound, C(18)H(24)N(2)O(2), the piperidine rings are in chair conformations. The crystal structure is stabilized by inter-molecular C-H?O hydrogen bonding. There are neither C-H?? nor ?-? inter-actions in the structure.

Project description:In the solid state the title Schiff base, 0.58C(28)H(20)N(2)O(2)·0.42C(28)H(20)N(2)O(2), exists both as the keto-imino and as the enol-amino tautomer, which is manifested in the disorder of the H atom in the intra-molecular hydrogen-bonded ring. The naphthalene ring systems show some distortion, which is consistent with the quinoid effect. The ratio of the enol form refined to 58?(5)%. The mol-ecule has crystallographically imposed symmetry: a twofold axis passes through the central benzene ring. Crystals are built up of layers parallel to (010). Stacking interactions between the layers involve only standard van der Waals attraction forces between apolar groups. The alignment of the aromatic rings in neighbouring layers shows a herringbone motif. A weak C-H?O inter-action is observed.

1,1'-(Propane-1,3-di-yl)bis-(3-phenyl-urea).

Project description:The title compound, C(17)H(20)N(4)O(2), has crystallographic inversion symmetry. In the crystal structure, inter-molecular hydrogen bonding between adjacent urea groups gives rise to infinite polymeric chains diagonally across the bc plane. With a centroid-centroid distance of 3.295?(2)?Å, ?-? stacking is present in the crystal along the same plane.

The angle at the methyl-ene C atom is 112.8?(1)°. The anion lies on a special position of m site symmetry; four F atoms lie on this mirror plane.

Project description:The mol-ecule of the title compound, C(22)H(18)N(4)O(2)S(2), lies across a crystallographic inversion centre. The central benzene ring forms dihedral angles of 29.39?(9) and 79.11?(12)°, respectively, with the thio-urea unit and the terminal phenyl ring. Intra-molecular N-H?O hydrogen bonds generate two S(6) ring motifs. In the crystal, mol-ecules are linked into chains along [10] by inter-molecular N-H?S hydrogen bonds.

The sheets are stacked along the a axis via ?-? inter-actions formed between the terminal benzene rings [centroid-centroid separation = 3.7276?(6)?Å].

Project description:In the title compound, C17H21N3O, the C-N bond lengths in the guanidine unit are 1.2889?(19), 1.3682?(19) and 1.408?(2)?Å, indicating double- and single-bond character. The N-C-N angles are 115.10?(13), 119.29?(15) and 125.61?(14)°, showing a deviation of the CN3 plane from an ideal trigonal-planar geometry. In the crystal, non-classical C-H?O hydrogen bonds between methyl H atoms and meth-oxy O atoms are present, generating centrosymmetric dimers running in the [101] direction.
