'''trans-Dichlorodiammineplatinum(II)' is the trans isomer of the coordination complex with the formula trans-PtCl2(NH3)2, sometimes called transplatin''. It is a yellow solid with low solubility in water but good solubility in dimethylformamide. The existence of two isomers of PtCl2(NH3)2 led Alfred Werner to propose square planar molecular geometry. It belongs to the molecular symmetry point group D2h.

Chloro(tetrahydrothiophene)gold(I), abbreviated (tht)AuCl, is a coordination complex of gold. Like the dimethyl sulfide analog, this compound is used as an entry point to gold chemistry. The tetrahydrothiophene ligand is labile and is readily substituted with other stronger ligands.

Dichlorobis(ethylenediamine)nickel(II) is the inorganic compound with the formula NiCl2(en)2, where en = ethylenediamine. The formula is deceptive: the compound is the chloride salt of the coordination complex [Ni2Cl2(en)4]2+. This blue solid is soluble in water and some polar organic solvents. It is prepared by ligand redistribution from [Ni(en)3]Cl2 and hydrated nickel chloride: 2 [Ni(en)3]Cl2 + NiCl2 → 3 NiCl2(en)2

chemical compound
