Write the name and formula of a species other than `NH_4^+` which involves simple covalent bonds and a coordinate bond.

Explanation

To answer the question, we need to identify a species that has both simple covalent bonds and a coordinate (or dative) bond.

### Step-by-Step Solution:

1. **Understanding Covalent and Coordinate Bonds**:
- A covalent bond is formed by the mutual sharing of electron pairs between atoms.
- A coordinate bond (also known as a dative bond) is formed when one atom donates both electrons to another atom that has an empty orbital.
