Not much is currently known about the structure of dark matter. For a start, it was never directly observed. There is only indirect evidence for dark matter. Therefore, it isn't know what types of structures it forms, if any.

Dark matter
Based on just a few simple things that popular news magazines mentionwhen they talk about the weird subject of dark matter, we're pretty safein assuming that dark matter has no electrical charge.-- No place in the universe is known to have dark matter.-- Dark matter is hypothesized ("just a theory") but has never been observed.-- It can't have an electrical charge, because if it did, then---- it would interact with other observed electrical charges and observed electromagnetic fields,------ which is exactly what it doesn't do,-------- which is why it has never been observed and is called "dark" matter.
Dark matter and dark energy have NOT been detected yet, so any ideas about detecting dark energy and dark matter, whether it be directly or indirectly, is speculation for now.
'Dark matter' and 'dark energy' have not been observed or proven yet.

Dark matter is known to exist, due to its gravitational effects. It has not been observed directly.It is believed to be some as-yet unknown particle, which doesn't interact at all, or only very little, with normal matter, or with light, via any force other than gravitation. Thus, for example, it won't absorb or emit light - light will pass right through it.
There is a lack of OBSERVED matter, but it is quite clear (due to gravitational effects), that dark matter indeed exists. There are all kinds of pieces of evidence in favor of dark matter. It isn't known yet what it is made of.
We know that dark matter exists because it got gravity, though it is invisible. It hold galaxy and Universes. There is a theory there many other parallel universe outside our universe and dark matter holds those universe up and some scientists says that dark matter are just mass of the matter of the parallel universe. It sounds crazy but that is the Law of Physics. However there is not exact explanation of what dark matter really is, so there are still Noble Prices for those who can come up with a reasonable explanation.
When the total amount of mass in a galaxy is computed, and the total amount of gravity is calculated there is a discrepancy. There appears to be more matter in the galaxy than what can be observed. Dark matter was theorized as being matter that exists but does not interact with electromagnetic radiation. Because of this, it cannot be seen. That is why it is called dark matter.
