In this work, firstly all maximally accretive extensions of the minimal operator generated by first-order linear symmetric multipoint quasi-differential operator expression in the direct sum of weighted Hilbert spaces of vector-functions defined at the left and right semi-infinite intervals are described. Later on, the structure of spectrum of such extensions is investigated.
