The developers of the Ground Zero mosque expect to raise $7.5 million this year, a drop in the bucket toward the $100 million needed for the project.

The projected contributions are expected to double to $15 million in 2012, according to the IRS application for tax-exempt status filed by Park51, the group behind the controversial community center and mosque.

A spokesman for Park51 refused to say how much had been raised since the project was announced a year ago.

The mosque and cultural center is to be located at the site of the former Burlington Coat Factory building on Park Place, a few blocks from Ground Zero. In order to go forward, the developers still need to buy half the site from Con Edison. They are still hashing out a price.

The developers say the mosque will be operated by a separate and independent nonprofit called PrayerSpace.

But there is no record that an organization named PrayerSpace has been incorporated in New York.
