What is the coordination number of chromium in K3[Cr(C2O4)3]?(a) 1(b)

1.	What is the coordination number of chromium in K3[Cr(C2O4)3]?(a) 1(b) 2(c) 3(d) 6I got this question in an interview for job.My doubt is from Definitions topic in portion Coordination Compounds of Chemistry – Class 12
Answer» The correct answer is (d) 6 The explanation: There are three oxalate groups attached to the central ION in the GIVEN compound, but SINCE oxalate is a didentate ligand, there are a total of 6 donor atoms to which the metal is directly bonded. THUS, the CN of Cr in K3[Cr(C2O4)3] is 6.
