  We report serendipitous detections of line emission with the Atacama Large
Millimeter/submillimeter Array (ALMA) in band 3, 6, and 7 in the central parsec
down to within 1" around Sgr A* at an up to now highest resolution (<0.5") view
of the Galactic Center (GC) in the sub-millimeter (sub-mm) domain. From the 100
GHz continuum and the H39\alpha emission we obtain a uniform electron
temperature around 6000 K for the minispiral. The spectral index of Sgr A* is ~
0.5 at 100 - 250 GHz and ~ 0.0 at 230 - 340 GHz. The bright sources in the
center show spectral indices around -0.1 implying Bremsstrahlung emission,
while dust emission is emerging in the minispiral exterior. Apart from CS,
which is most widespread in the center, H13CO+, HC3N, SiO, SO, C2H, CH3OH, 13CS
and N2H+ are also detected. The bulk of the clumpy emission regions is at
positive velocities and in a region confined by the minispiral northern arm,
bar and the sources IRS 3 and 7. Although partly spatially overlapping with the
radio recombination line (RRL) emission at same negative velocities, the
relation to the minispiral remains unclear. A likely explanation is an
infalling clump consisting of denser cloud cores embedded in diffuse gas. The
central association of clouds (CA) shows three times higher CS/X (X: any other
observed molecule) ratios than the circumnuclear disk (CND) suggesting a
combination of higher excitation, by a temperature gradient and/or IR-pumping,
and abundance enhancement due to UV- and/or X-ray emission. Hence, we conclude
that this CA is closer to the center than the CND is to the center. Moreover,
we find molecular emission at velocities up to 200 km s-1. ...
