I went the journal site for the source of the style, and they don’t ask for a tabbed output, but for this which I cut and pasted from their author instructions:
 a) H. J. Ache, Angew. Chem. 1989, 101, 1–21; Angew. Chem. Int. Ed. Engl. 1989, 28, 1–20; b) H. Frey, Angew. Chem. 1998, 110, 2313–2318; Angew. Chem. Int. Ed. 1998, 37, 2193–2197.
 A. Kraft, Chem. Commun. 1996, 77–79, and references therein; Sci. Am. 1984, 250(4), 7–8; B. Krebs, H. U. Hürter, Acta Crystallogr. Sect. A 1981, 37, 163; G. Eulenberger, Z. Naturforsch. B 1981, 36, 521; D. Bruss, Appl. Phys. B, DOI 10.1007/s003409900185.
And I can get exactly that by replacing the tab with a space in the style’s layout, adding an end of paragraph to the layout following box, and applying NONE to the hanging indents and saving the style and adding a space in front of the Author field in each of the bibliography templates. In fact, if you copy and paste the references from an article from the journal, while it looks all the world like a tabbed hanging indent, it has a space and each line is a paragraph. In the HTML version it is a table.
So I highly recommend people focus much more on the “content” than getting a space in the right place. Once it is accepted, the publishing editor will make sure the references align correctly.
I attach the style I modified, if you want to use it.
(I was unable to generate the correct spacing using the hanging indented settings in the layout, but I didn’t try all that hard once I read the author instructions.)
