Set Company Name while creating contact using MS CRM web api + C#

I am getting "Bad Request" response while creating contact with company name.

Code I am using  to set account company is below.

_webApiURL = [Organization URI]/api/data/v8.2/

contact.Add("parentcustomerid@odata.bind", string.Format("{0}accounts(b6bc8b98-14e7-e611-8103-5065f38ac921)", _webApiURL));
