  Using the new 23 GHz receivers at the Very Large Array (VLA), we have
detected NH3(6,6) emission (nu=25.056025 GHz) from hot (>150 K) molecular
clouds in the central 10 pc of the Galaxy. This is the first successful
detection of NH3(6,6) with the VLA. The brightest emission comes from a region
interior to the ``circumnuclear disk'' (CND), less than 1.5 pc in projected
distance from Sgr A*. This region does not show molecular emission from lower
energy transitions such as NH3(1,1) and (2,2), HCN(1-0) and HCO+(1-0). Line
ratios of NH3(6,6) and (3,3) emission as well as NH3(6,6) line widths have peak
values within 1.5 pc of Sgr A*, indicating that the gas is physically close to
the nucleus. NH3(6,6) is also detected towards many features outside the CND
observed in NH3(1,1), (2,2), and (3,3). These features tend to lie along ridges
of gas associated with Sgr A East or the massive ``molecular ridge'' that
connects the ``20 km/s'' and ``50 km/s'' giant molecular clouds (GMCs).
