چکیده
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.

In the title compound, C(13)H(18)N(2)O(2)S, the 4-meth-oxy-benzoyl fragment is approximately planar [maximum deviation = 0.057 (2) Å] and twisted relative to the thio-amide fragment, forming a dihedral angle of 86.62 (6)°. The two Csp(2)-Nsp(2) bonds in the thio-urea unit differ significantly in length [1.327 (2) and 1.431 (2) Å]. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into ch...

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 bon...

The two title compounds, C28H26N2O2, (I), and C27H22BrClN2O2, (II), differ in their substituents, viz.4-methyl-phenyl and benzoyl rings in (I) replaced by 2-chloro-phenyl and 4- bromo-benzoyl, respectively, in (II). A significant difference between the two mol-ecules is found in the deviation of the benzoyl O atom from the least-squares plane of the ring to which it is attached [0.593 (4) and 0...

The synthesis of the title compound, C(12)H(15)BrN(2)OS, involves the reaction of 4-bromo-benzoyl chloride with potassium thio-cyanate in dry acetone, followed by condensation of 4-bromo-benzoyl isothio-cyanate with diethyl-amine. The carbonyl and thio-carbonyl bond lengths indicate that these correspond to double bonds. The short C-N bond lengths reveal the effects of resonance in this part of...
