2-Benzoyl-4-chloro-aniline thio-semi-carbazone.

ABSTRACT: In the title compound, C14H13ClN4S, obtained from a reaction of 2-benzoyl-4-chloro-aniline with thio-semicarbazide in ethanol, the dihedral angle between the aromatic rings is 81.31 (13)°. In the crystal, the mol-ecules are linked by three N-H⋯S hydrogen bonds, forming centrosymmetric rings with set-graph motif R 2 (2)(8) and R 2 (2)(18), and resulting in the formation of a two-dimensional network lying parallel to (010).

Pyridine-2-carbaldehyde thio-semi-carbazone.

Project description:The asymmetric unit of the title compound, C(7)H(8)N(4)S, contains two independent mol-ecules with slightly different conformations; the dihedral angles between the pyridine ring and mean plane of the thio-semicarbazone unit in the two mol-ecules are 2.88?(5) and 6.30?(5)°. Inter-molecular N-H?N and N-H?S hydrogen bonds link the mol-ecules into layers parallel to the ab plane.

Ferrocene-1-carbaldehyde thio-semi-carbazone.

Project description:The asymmetric unit of the title compound, [Fe(C(5)H(5))(C(7)H(8)N(3)S)], consists of two crystallographically independent mol-ecules, A and B. The cyclo-penta-dienyl (Cp) rings in both mol-ecules adopt an eclipsed conformation and are parallel to each other, forming dihedral angles of 2.5?(3) and 1.1?(3)°, respectively. The mean plane of the semicarbazone group is coplanar with the attached Cp ring in mol-ecule A, whereas it is twisted away in mol-ecule B. In the crystal structure, inter-molecular N-H?S hydrogen bonds link the mol-ecules into two-dimensional planes parallel to the ab plane. The structure is further consolidated by C-H?? inter-actions.

3,4-Dihydroxy-benzaldehyde thio-semi-carbazone.

Project description:The asymmetric unit of the title compound, C(8)H(9)N(3)O(2)S, contains three independent mol-ecules which are stacked approximately over each other. In the crystal structure, centrosymmetric pairs of mol-ecules are formed through inter-molecular hydr-oxy-hydr-oxy O-H?O and hydr-oxy-sulfur O-H?S hydrogen bonds which are, in turn, linked into a two-dimensional network by N-H?O(hydr-oxy) hydrogen bonds.

3-Methoxy-benzaldehyde thio-semi-carbazone.

Project description:The title compound, C(9)H(11)N(3)OS, was prepared by the reaction of 3-methoxy-benzaldehyde and thio-semicarbazide. The benzyl-idene ring and the thio-semicarbazone fragment are slightly twisted, making a dihedral angle of 14.1 (1)°. A weak intra-molecular N-H⋯N hydrogen bond may influence the conformation of the mol-ecule. Inter-molecular N-H⋯S hydrogen bonds build up a three-dimensional network.

4-Methyl-benzaldehyde thio-semi-carbazone.

Project description:The title compound, C(9)H(11)N(3)S, was prepared by reacting 4-methyl-benzaldehyde with thio-semicarbazide. An intra-molecular N-H⋯N hydrogen bond helps to establish the observed mol-ecular conformation. The crystal packing is realized by inter-molecular N-H⋯S hydrogen bonds.

1-(Thio-phen-2-yl)ethanone thio-semi-carbazone.

Project description:The title compound, C(7)H(9)N(3)S(2), crystallizes with two unique mol-ecules in the unit cell, both present as thio-semicarbazide tautomers. The mol-ecules differ principally in the dihedral angles between the thio-phene ring planes and the planes through the non-H atoms of the hydrazinecarbothio-amide units, viz. 9.80?(8)° for one mol-ecule and 19.37?(7)° for the other. The hydrazinecarbothio-amide units are reasonably planar, with r.m.s. deviations of 0.001Å for each of the mol-ecules. In the crystal, N-H?S hydrogen bonds link like mol-ecules into R(2) (2)(8) inversion dimers. A three-dimensional network structure is generated by additional N-H?S hydrogen bonds and weak C-H?S contacts between the unique mol-ecules.

Ferrocene-1-carbaldehyde 4-ethyl-thio-semi-carbazone.

Project description:The asymmetric unit of title compound, [Fe(C(5)H(5))(C(9)H(12)N(3)S)], contains two crystallographically independent mol-ecules, A and B. The two cyclo-penta-dienyl (Cp) rings are parallel to each other in both mol-ecules, forming dihedral angles of 2.3?(3) and 1.0?(3)°, respectively, and adopt an eclipsed conformation. The mean plane of the semicarbazone group is twisted slightly away from the attached Cp ring in both mol-ecules, the dihedral angles between the mean plane and the Cp ring being 15.3?(2) and 10.8?(2)°. The ethyl group in mol-ecule A is coplanar with the mean plane of the semicarbazone group [C-N-C-C torsion angle = -175.2?(4)°], whereas it is nearly perpendicular in mol-ecule B [C-N-C-C torsion angle = 84.8?(6)°]. In the crystal structure, inter-molecular N-H?S hydrogen bonds link the mol-ecules into dimers. These dimers are further linked into chains via inter-molecular C-H?S hydrogen bonds. The crystal studied was a non-merohedral twin with a refined ratio of the twin components of 0.265?(2):0.735?(2).
