Question

Give the IUPAC name of ${\left[ {{\text{Ti}}{{\left( {{{\text{H}}_2}{\text{O}}} \right)}_6}} \right]^{3 + }}$. Draw cis and trans isomers of \[[Pt(N{H_3})(C{l_2})]\].

Answer 1

Hint: More complex coordination compounds are made up of an atom or ion (usually a metal) and a ligand-like sequence of bound molecules or anions. The donor atom is the atom in a ligand that is bound to the central atom or ion. Several donor atoms, which may be the same or different, are connected to a standard complex. The coordinate covalent bonds (dipolar bonds) between the ligands and the central atom are referred to as coordination.

Complete answer: The ligands are numbered before the metal ion by naming a complex ion.
In the following sequence, write the names of the ligands: neutral, negative, positive. If several ligands with the same charge class exist, they are called alphabetically. (Numerical prefixes have little impact on the ordering.)
The number of occurrences of several monodentate ligands is indicated by a prefix: di-, tri-, tetra-, penta-, or hexa. Polydentate ligands (e.g., ethylenediamine, oxalate) obtain bis-, tris-, tetrakis-
 ${\left[ {{\text{Ti}}{{\left( {{{\text{H}}_2}{\text{O}}} \right)}_6}} \right]^{3 + }}$=
Metal = Titanium
Ligand = Water = hexaaqua
Charge = +3
IUPAC Name = hexaaquatitanium(III)
Isomerism
"Cis" and "trans" are Latin prefixes that mean "this side of" and "the other side of," respectively. In chemistry, cis denotes functional groups that are on the same side of the carbon chain, while trans denotes functional groups that are on opposite sides of the carbon chain.
The two ligands are on the same side of the complex of cis molecules. Similar ligands are on the opposite sides of the molecules of trans molecules. Stereoisomerism does not exist in tetrahedral molecules. The isomer is called facial, or fac, when three similar ligands share one face.

Note:
"Cis" and "trans" are Latin prefixes that mean "this side of" and "the other side of," respectively. In chemistry, cis denotes functional groups that are on the same side of the carbon chain, while trans denotes functional groups that are on opposite sides of the carbon chain.
