Not that the distinction bears much value making: They funded the proto-Nazis.
In the time period in question (After WW1, Wiemar Germany) the social democrats were in direct coalition with right wing paramilitaries.
Those paramilitaries did some extrajudicial killings and some just so happened to form things like the S.A. and the Nazi party. (And tried to overthrow the social democrats government a number of times by military coup.) Erich Ludendorff is a notable figure to this period.
But by the time the proto-Nazis had murdered themselves and others enough to become the Nazis, no, the social democrats were no longer in alliance, but mostly after the second coup attempt.
