Ferrocene-1-carbaldehyde thio­semi­carbazone

The asymmetric unit of the title compound, [Fe(C5H5)(C7H8N3S)], consists of two crystallographically independent mol­ecules, A and B. The cyclo­penta­dienyl (Cp) rings in both mol­ecules 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 mol­ecule A, whereas it is twisted away in mol­ecule B. In the crystal structure, inter­molecular N—H⋯S hydrogen bonds link the mol­ecules into two-dimensional planes parallel to the ab plane. The structure is further consolidated by C—H⋯π inter­actions

Bis(1-ferrocenylmethyl­idene-4-phenyl­thiosemicarbazidato-κ2 N 1,S)zinc(II) monohydrate

In the title compound, [Fe2Zn(C5H5)2(C13H11N3S)2]·H2O, the ZnII ion is in a distorted tetra­hedral geometry being coordinated by two thio­semicarbazone ligands via N and S atoms. One of the Cp rings is disordered over two positions with occupancies of 0.55 and 0.45. The dihedral angle between the substituted Cp rings is 56.1 (5)° and the two phenyl rings are orientated at a dihedral angle of 41.7 (4)°. In the crystal structure, inter­molecular O—H⋯S, N—H⋯O and C—H⋯N hydrogen bonds link the mol­ecules into chains along the b axis. The structure is further consolidated by O—H⋯π inter­actions

Ferrocene-1-carbaldehyde 4-ethyl­thio­semi­carbazone

The asymmetric unit of title compound, [Fe(C5H5)(C9H12N3S)], contains two crystallographically independent mol­ecules, A and B. The two cyclo­penta­dienyl (Cp) rings are parallel to each other in both mol­ecules, 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 mol­ecules, the dihedral angles between the mean plane and the Cp ring being 15.3 (2) and 10.8 (2)°. The ethyl group in mol­ecule 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 mol­ecule B [C—N—C—C torsion angle = 84.8 (6)°]. In the crystal structure, inter­molecular N—H⋯S hydrogen bonds link the mol­ecules into dimers. These dimers are further linked into chains via inter­molecular 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)

Poly[[aquadi-μ3-malonato-hexaphenyl­ditin(IV)] acetone solvate]

The asymmetric unit of the title polymeric complex, {[Sn2=(C6H5)6(C3H2O4)(H2O)]·C3H6O}n, comprises of two Sn cations, one malonate anion and a non-coordinating acetone solvent mol­ecule. Both crystallographically independent Sn cations are five-coordinated by two O and three C atoms in a distorted trigonal-bipyrimidal geometry. One of the Sn cations is bridged by the malonate units, affording polymeric chains which run along [001]. Weak intra­molecular C—H⋯π inter­actions stabilize the mol­ecular structure. In the crystal structure, adjacent chains are inter­connected by inter­molecular O—H⋯O and C—H⋯O hydrogen bonds into a three-dimensional supra­molecular structure. A weak inter­molecular C—H⋯π inter­action is also observed

Bis(ferrocenecarbaldehyde thio­semi­carbazonato-κ2 N 1,S)zinc

In the title compound, [Fe2Zn(C5H5)2(C7H7N3S)2], the Cp rings of each ferrocene residue have a nearly eclipsed conformation. The two thio­semicarbazone ligands each coordinate the Zn atom in a bidentate mode via the N and S atoms, thereby defining a distorted tetra­hedral environment. N—H⋯S, N—H⋯N, C—H⋯S and C—H⋯N intra- and intermol­ecular inter­actions connect the mol­ecules into a two-dimensional array parallel to (010)

Bis(ferrocenecarbaldehyde 4-methylthiosemicarbazonato-κ2N1,S)zinc(II) methanol solvate

In the title compound, [Fe2Zn(C5H5)2(C8H9N3S)2]·CH3OH, the dihedral angles between the substituted and unsubstituted cyclopentadienyl rings are 89.34 (8) and 85.73 (9)°, respectively. The two Zn/S/C/N/N five-membered rings adopt envelope conformations, with the ZnII atom at the flap. Each methanol solvent molecule is linked to three ferrocene groups via intermolecular O—H...N, N—H...O and C—H...O hydrogen bonds. The crystal structure is further consolidated by C—H...π interactions
