Is this what you're talking about?


And do you know anything else about it?  Like the reaction or anything?

May be, because both compounds are  a bit impure. Moreover, both compounds are susceptible to light..
May be  the influence of different inductive electronic effect should be taken into account..
Compound (c3H3Ag)is not exactly white - weisser means whitish.

Gmelin Handbuch generally says "Die farblosen alkinyle vom Typ AgCCR sind lichtempfindlich"
so they should be white (colourless). In JACS 78 (1956) 1675-8 the derivatives C3, C6 and C8
are white.
