In this paper, several infinite families of codes over the extension of non-unital non-commutative rings are constructed utilizing general simplicial complexes. Thanks to the special structure of the defining sets, the principal parameters of these codes are characterized. Specially, when the employed simplicial complexes are generated by a single maximal element, we determine their Lee weight distributions completely. Furthermore, by considering the Gray image codes and the corresponding subfield-like codes, numerous of linear codes over Fq are also obtained, where q is a prime power. Certain conditions are given to ensure the above linear codes are (Hermitian) self-orthogonal in the case of q=2, 3, 4. It is noteworthy that most of the derived codes over Fq satisfy the Ashikhmin-Barg's condition for minimality. Besides, we obtain two infinite families of distance-optimal codes over Fq with respect to the Griesmer bound.
