I know in the literature all papers that describe syllable structures in Arabic, referred to the following five patterns:
CV, CVV, CVC, CVVC, CVCC, and in some dialects CCV(V)C(C).
However, all these papers considered VV as the longe vowel, NOT two different vowels in a sequence!!
Therefore, could we consider Arabic as a language with only three core syllabic structures: CV, CVC, CVCC, where the CC is only a true consonant cluster with two different consonants, and V is the vowel either long or short???
