By definition, a compound is always neutral. If the polyatomic chemical entity has a charge, it is no longer a compound, but is now a polyatomic ion. Ionic compounds and molecular compounds are also neutral in charge. The word "ionic" is just referring to the type of chemical bond in the molecule.
Polyatomic ions are not compounds because they are not electrically neutral, and they are not elements because they can be broken down into other chemical constituents -- the actual elements.
Since Group 1A monatomic ions have a charge of 1+, only a polyatomic ion with a charge of 1- can combine to form a compound in which the monatomic ions and polyatomic ions are present in a 1 to 1 ratio. The following polyatomic ions with a charge of 1- can form a neutral compound when combined with a group of 1A monatomic ion in a 1 to 1 ratio.acetate - C2H3O2-bicarbonate (or hydrogen carbonate) - HCO3-bisulfate (or hydrogen sulfate) - HSO4-chlorate - ClO3-chlorite - ClO2-cyanate - OCN-cyanide - CN-dihydrogen phosphate - H2PO4-hydroxide - OH-nitrate - NO3-nitrite - NO2-perchlorate - ClO4-permanganate - MnO4-thiocyanate - SCN- Source: http://chemistry.about.com/od/chartstables/tp/common-polyatomic-ions.htm
Carbon monoxide is not a polyatomic ion. In fact, it isn't an ion at all! Carbon monoxide does consist of two different elements (and is therefore a bimolecular compound), but it is a neutral species.

Ionic compounds contain ions, there are no neutral molecules. These are often charged atoms as in NaCl but may be polyatomic ions such as NH4+ which contains covalent bonds
Sodium sulfate is an ionic compound, composed of monatomic and monovalent sodium cations and polyatomic and divalent sulfate anions. The anions are internally covalently bonded, but are not compounds because they are not electrically neutral.
A molecule is neutral, an ion has an electrical charge.
In any neutral compound, this number must be zero.
