1-[(Z)-1-Ferrocenyl­ethyl­idene]thio­carbonohydrazide

In the title compound, [Fe(C₅H₅)(C₈H₁₁N₄S)], the cyclo­penta­dienyl (Cp) rings of the ferrocene unit are close to being eclipsed. They are inclined to one another at an angle of 1.95 (2)° and lie 3.309 (2)Å away from each other. The ethyl­idene­thio­carbonohydrazide fragment is planar, with an r.m.s. deviation of 0.0347 (2) Å from the mean plane of its eight non-H atoms, and makes dihedral angles of 21.78 (1) and 19.97 (1)° with respect to the two Cp rings. The mol­ecule adopts a trans geometry about the C=N double bond. In the crystal, N—H...(N/S) and C—H...S inter­actions stack the mol­ecules in an inverse fashion along the b axis.

cis-Dichloridobis(N,N,N′,N′-tetra­methyl­ethane-1,2-diamine)­platinum(II)

In the title complex, [PtCl₂(C₆H₁₆N₂)], the Pt^II atom adopts a distorted cis-PtN₂Cl₂ square-planar coordination geometry. The five-membered chelate ring adopts a twisted conformation. In the crystal, weak C—H...Cl hydrogen bonds link the mol­ecules into (001) sheets.

Ethyl (Z)-2-chloro-2-[2-(4-meth­oxy­phenyl)hydrazin-1-yl­idene]acetate

The mol­ecule of the title compound, C₁₁H₁₃ClN₂O₃, is planar (r.m.s. deviation = 0.0587 Å for non-H atoms) and adopts a Z conformation about the C=N double bond. In the crystal, mol­ecules are linked via an N—H...O hydrogen bond, forming zigzag chains propagating along [010]. These chains are consolidated by C—H...O hydrogen bonds.

(Z)-Ethyl 2-chloro-2-[2-(4-methyl­phen­yl)hydrazinyl­idene]acetate

The mol­ecule of the title compound, C₁₁H₁₃ClN₂O₂, is approximately planar (r.m.s. deviation = 0.099 Å for non-H atoms) and adopts a Z conformation about the C=N double bond. In the crystal, mol­ecules are linked by N—H...O and C—H...O hydrogen bonds to the same O-atom acceptor, forming zigzag chains propagating along [010]. These inter­actions give rise to R₂¹(6) loops.
