I found Chinese: A Linguistic Introduction by Sun Chaofen very useful. I think it was a teacher who recommended it to me. It has two chapters on syntax. It was very easy to read for both language learners and linguists (I was studying both at the time).

Chinese Grammar Wiki is good too, they have standalone pages for most sentence structures. A good starting point would be:

https://resources.allsetlearning.com/chinese/grammar/Grammar_structures

https://resources.allsetlearning.com/chinese/grammar/Basic_sentence_order

https://resources.allsetlearning.com/chinese/grammar/Sentence_Patterns

I personally don't like the wiki format, I prefer books and articles, but the wiki is always good for consultation.
