Assertion `:` is named as tetrakis ( ethylene diamine ) `mu`- hydroxo - imido dicobalt (III) ion.
Reason `:` In naming polynuclear complexes i.e., containing two or more metal atoms joined by bridging ligands, the word `mu` is add with hyphen before the name of such ligands.

Assertion : is named as tetrakis (ethylene- diammine) mu-"hydroxo"-mu-"imido dicobalt (III) ion" . Reason : In naming polynuclear complexes i.e., containing two or more metal atoms joined by bridging ligands, the word mu is added with hyphen before the nane of such ligands.

Assertion:In a complex prefixes cis- and trans - are used to designate adjacent and opposite geometric location of the ligands Reason: With in the coordination sphere ligands are named after the metal atom (or) ion

The IUPAC name of [Co(H_2NCH_2CH_2NH_2)_2 (NO_2)NO_5 is bis(enthane-1,2-diamine) dinitrito-N-cobalt(III) nitrate.It follows the following rules that. (a)Cation is named first followed by anion. (b) Ligands are named in an alphabetical order before the name of the central atom/ion. ( c)Name of anionic ligands end in "o" (ex.chlorido) those of neutral (and if cation) ligands are the same except aqua for H_2O , ammine for NH_3 etc. (d)Prefixes mono,di,tri,etc.are used to indicate the number of individual ligand.When the name of the ligands include a numerical prefix, then terms bis, tris, tetrakis are used. (e)Oxidation state of the metal is indicated by Roman numeral in parenthesis. (f) For cationic and neutral complexes, the metal is named same as the element and for anionic complex, the name of metal ends with suffix-ate.For some metals, the Latin names are used in the complex anions , e.g., ferrate for Fe, argentate for silver etc. The correct IUPAC name of the coordination compound [Pt(NH_3)_2Cl(NH_2CH_3)] is :
