i am a chinese female chem-researcher ，and my english is very poor，if i said something wrong ，please dont laugh at me 。
i am a researcher ，and i wanna research a  chemical substance  named "Guanidinium formate" ,it is used for SCR system in diesel car，but i havent found any datas on the internet。unconsciously，i found this website by google ，so i hope someone can help me in this forum。
if someone know this  material，please tell me the physical property 、 chemical property and how to synthetize it 。thk u 。

suggestion：u can search the substance by Reaxys or scifinder。

and who can tell me some other famous forum for chemistry

Well, this forum is one of the better ones, the Moderators work hard to keep the cruft (useless postings) out.  I did a Google for you and had better luck -- http://www.td.mw.tum.de/tum-td/de/forschung/themen/low_nox_scr  That contains a nice abstract, and you can use the author's name for more help.  If Google just isn't working for you, you'll have to go a more traditional route -- perhaps your academic department would like to get in contact with the author, or his university department on a more personal level.  Or if your university can get the article reprint, you can use the bibliography to search for more articles you can use.

Guanidinium formate is a salt. If you can obtain any salt from acid and base you can also obtain this one. The only problem is a synthesis of anhydrous salt but I think that anhydrous formic acid is in your hand.

thk u very much  for reply my question。of course you r right，the Guanidinium formate is a salt，the structure is here：

as i know ，the Guanidinium formate can be combounded by formic acid and guanidine，but i think it's a drastic reaction，and guanidine is very dangerous and expensive。the other way to obtain the Guanidinium formate is combounded by urea and ammonium formate。
the reaction equation is ：2(NH2CN)2+NH4CO2→NH2(NH)NHC(NH)NH2•CO2H      the same as compound Guanidine Nitrate。

can someone agree with  my idea？

but i think it's a drastic reaction

Just mixing is a drastic reaction?

2(NH2CN)2+NH4CO2

both compounds (urea and ammonium formate) show different formulas!
