  The primary focus of the current study is to explore the geometrical
properties of the Vaidya-Bonner-de Sitter (briefly, VBdS) spacetime, which is a
generalization of Vaidya-Bonner spacetime, Vaidya spacetime and Schwarzschild
spacetime. In this study we have shown that the VBdS spacetime describes
various types of pseudosymmetric structures, including pseudosymmetry due to
conformal curvature, conharmonic curvature and other curvatures. Additionally,
it is shown that such a spacetime is 2-quasi-Einstein, Einstein manifold of
level 3, generalized Roter type, and that conformal 2-forms are recurrent. The
geometric features of the Vaidya-Bonner spacetime, Vaidya spacetime, and
Schwarzschild spacetime are obtained as a particular instance of the main
determination. It is further established that the VBdS spacetime admits almost
Ricci soliton and almost \eta-Yamabe soliton with respect to non-Killing vector
fields. Also, it is proved that such a spacetime possesses generalized
conharmonic curvature inheritance. It is interesting to note that in the VBdS
spacetime the tensors Q(T,R), Q(S,R) and Q(g,R) are linearly dependent.
Finally, this spacetime is compared with the Vaidya-Bonner spacetime with
respect to their admitting geometric structures, viz., various kinds of
symmetry and pseudosymmetry properties.
