@user3306356 though 不高不兴 is understandable, it's definitely unusual. If it's spoken by someone especially by a non native speaker, I would think that they say something wrong. So, I would not suggest the non-standard phrases like 不高不兴  to the Chinese learners here.

<p><strong>Oxford</strong> gives three usages for this construct:</p>

  <p>① [used to make an emphatic negative form of two words identical or similar in meaning]</p>
  
  <p>不骄不躁

  <p>不慌不忙

  <p>不知不觉

  <p>不冷不热

@Hashamyim If you have Pleco (android/iOS app) you can search "不..." and you should find a good explanation for free.

<p>I have recently come across quite a few instances of polysyllabic adjectives being split up and preceded by 不s, e.g.</p>

<p>清楚 -> 不清不楚</p>

<p>高兴 -> 不高不兴</p>

<p>I guess this is simply a variation of not+adj. but does anyone know what the specific intention behind the construction is?
Many thanks,

The structure 不...不... is not standard, in my opinion. It doesn't work for all the adjectives. For example, 不高不兴 doesn't sound right.

You might have to learn those phrases by rote. Otherwise, it's easy to say something wrong. Better you hear it from others(native speakers), then you use it for safe.
