This article investigates square-nonagonal multifigurative numbers, a class of figurative numbers that belongs simultaneously to both square and nonagonal figurative numbers. Initially, the recurrence formula, the generating function, and the expression of the general term of the sequence are presented. Next, the process of complexification through the introduction of imaginary units is studied, which allows generalizations to higher dimensions. The two-dimensional, three-dimensional, and finally, t-dimensional relations are discussed, highlighting how such extensions expand the structural properties of these numbers and open perspectives for the study of other multifigurative number sequences.
