Oxalate phosphate
Chemical compound containing oxalate and phosphate anions
Na2 Fe(C2 O4 )(HPO4 ) crystal structure
The oxalate phosphates are chemical compounds containing oxalate and phosphate anions . They are also called oxalatophosphates or phosphate oxalates. Some oxalate-phosphate minerals found in bat guano deposits are known.[ 1] Oxalate phosphates can form metal organic framework compounds.
Related compounds include the arsenate oxalates,[ 2] [ 3] and phosphite oxalates,[ 4] oxalatomethylphosphonate,[ 5] and potentially other oxalate phosphonates.
